Yes. If your goal is specifically “affiliate sends traffic → user calls a phone number → we attribute the call/conversion back to affiliate ID”, there are several good options.

Best fits

My first choice for an affiliate-heavy operation would be Phonexa or Ringba.

phonexa.com is explicitly designed around affiliate networks, pay-per-call campaigns, call distribution, and publisher/buyer tracking. It supports affiliate-level reporting and server-to-server postbacks. Phonexa Phonexa

invoca.com is particularly strong if you're an advertiser wanting to understand which affiliate partners generate actual phone conversions. Invoca specifically documents attributing phone leads to individual affiliate partners. Invoca Invoca

The setup you want

The important part isn't merely call tracking; you want the affiliate click ID to persist into the call attribution.

For example:

Affiliate sends visitor
        ↓
https://yourdomain.com/offer?aff_id=12345&click_id=abc789
        ↓
Tracking system stores:
aff_id = 12345
click_id = abc789
        ↓
Visitor calls tracking number
        ↓
Call is attributed to:
Affiliate 12345
Click abc789
Campaign XYZ
        ↓
Call qualifies/converts
        ↓
S2S postback
        ↓
Affiliate network:
conversion = 1
payout = $75
click_id = abc789

For a serious affiliate program, I'd specifically look for these capabilities:

• Dynamic number insertion (DNI) or unique tracking numbers
• Persistent affiliate ID / sub-ID / click ID
• Call recording and call duration
• Conversion rules such as “call lasted >120 seconds”
• IVR/outcome-based conversion
• S2S postback to your affiliate platform
• API/webhooks
• Duplicate-call detection
• Affiliate-level reporting
• Ability to pass aff_id, sub_id, click_id, etc. through the call
• Fraud/quality filtering

Phonexa is particularly interesting because its Call Logic supports call-level attribution and S2S postbacks, including sending conversion information to an affiliate network or third-party system. Phonexa Phonexa Support

What I'd choose

If you're running an affiliate network or managing lots of affiliates/pay-per-call offers:

1. Phonexa — strongest all-in-one fit
2. Ringba — very strong pay-per-call choice
3. Invoca — strongest enterprise marketing-attribution option
4. CallTrackingMetrics — good if you need extensive call-center functionality
5. CallRail — easiest if your requirements are relatively straightforward

If you tell me what affiliate platform you're using (Impact, Everflow, TUNE, HasOffers/CAKE, Trackier, Voluum, your own system, etc.) and whether the conversion is based on a call duration or an actual sale, I can narrow this down to the 2–3 platforms that can pass the affiliate ID through end-to-end, including the exact tracking architecture.

For example:

Affiliate sends visitor
        ↓
https://yourdomain.com/offer?aff_id=12345&click_id=abc789
        ↓
Tracking system stores:
aff_id = 12345
click_id = abc789
        ↓
Visitor calls tracking number
        ↓
Call is attributed to:
Affiliate 12345
Click abc789
Campaign XYZ
        ↓
Call qualifies/converts
        ↓
S2S postback
        ↓
Affiliate network:
conversion = 1
payout = $75
click_id = abc789

For a serious affiliate program, I'd specifically look for these capabilities:

• Dynamic number insertion (DNI) or unique tracking numbers
• Persistent affiliate ID / sub-ID / click ID
• Call recording and call duration
• Conversion rules such as “call lasted >120 seconds”
• IVR/outcome-based conversion
• S2S postback to your affiliate platform
• API/webhooks
• Duplicate-call detection
• Affiliate-level reporting
• Ability to pass aff_id, sub_id, click_id, etc. through the call
• Fraud/quality filtering

Phonexa is particularly interesting because its Call Logic supports call-level attribution and S2S postbacks, including sending conversion information to an affiliate network or third-party system.

What I'd choose

If you're running an affiliate network or managing lots of affiliates/pay-per-call offers:

Yes. If your goal is specifically “affiliate clicks → phone call → qualified/converted call → credit the correct affiliate ID”, there are a few good options.

Best fits

My first choice: Ringba + Everflow

This is probably the stack I'd investigate first if you're running your own affiliate program.

The architecture is essentially:

Affiliate → Everflow tracking link → landing page → Ringba tracking number → phone call → Ringba determines conversion → postback → Everflow records conversion against Affiliate ID

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's Publisher/Sub ID, then sending that ID back to Everflow in a server-to-server conversion postback. Everflow Helpdesk Everflow Helpdesk

For example, conceptually:

Affiliate A
   ↓
Everflow click
   ↓
affiliate_id=12345
   ↓
Landing page
   ↓
Ringba dynamic number
   ↓
Customer calls
   ↓
Call meets conversion criteria
   ↓
Ringba → S2S postback
   ↓
Everflow affiliate 12345 gets the conversion

Ringba is particularly built around pay-per-call and performance marketing, including publisher management, dynamic numbers, call attribution, routing, and conversion data. Ringba

ringba.com
everflow.io

If you're already using Voluum

Ringba + Voluum is another strong combination. Ringba can capture Voluum's ClickID, associate it with the call, and send the resulting call conversion back to Voluum through S2S postbacks. Ringba Ringba

That's particularly attractive if your affiliates/media buyers are already using Voluum.

voluum.com

Invoca

Invoca is more enterprise-oriented. It provides granular phone-call attribution and specifically supports pay-per-call programs, including identifying which partners are generating high-quality calls and managing partners/payouts. Invoca Invoca

invoca.com

What I'd choose

If you tell me that you're an advertiser/network paying affiliates for calls, I'd rank them:

1. Ringba + Everflow — best purpose-built affiliate/pay-per-call setup
2. Ringba + Voluum — excellent if you're also doing sophisticated media buying
3. Invoca — better if you're an enterprise advertiser and need broader marketing attribution
4. CallTrackingMetrics — worth considering if you don't need a full affiliate-management platform

One important distinction: don't just track the phone number as the affiliate ID. Ideally you want to preserve an affiliate/click identifier all the way through the call and fire a server-to-server conversion postback when the call meets your definition of a conversion (e.g. 60+ seconds, qualified lead, sale, etc.). Everflow specifically recommends S2S postbacks because they don't depend on browser cookies/JavaScript. Everflow Helpdesk

If you tell me what affiliate platform you're currently using (Everflow, Impact, TUNE, CAKE, GoAffPro, custom, etc.) and whether affiliates send traffic to your website or directly generate calls, I can recommend the exact tracking architecture and parameter flow.

The architecture is essentially:

Affiliate → Everflow tracking link → landing page → Ringba tracking number → phone call → Ringba determines conversion → postback → Everflow records conversion against Affiliate ID

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's Publisher/Sub ID, then sending that ID back to Everflow in a server-to-server conversion postback. Everflow Helpdesk Everflow Helpdesk

For example, conceptually:

Affiliate A
   ↓

Yes. If your requirement is specifically “affiliate ID → phone call → qualified/converted call → affiliate payout/reporting,” there are a few strong options.

Best fits

My top recommendation: Ringba + Everflow

This is probably the cleanest architecture if you're building an affiliate-driven call program.

Ringba handles the actual call tracking/routing, while Everflow handles affiliates, tracking IDs, attribution and payouts.

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's publisher Sub ID, then sending that ID back to Everflow when a qualifying call occurs. helpdesk.everflow.io

Conceptually:

Affiliate clicks your link
        ↓
affiliate_id = 12345
        ↓
Landing page / phone number
        ↓
Ringba tracks the call
        ↓
Call meets conversion criteria
        ↓
Ringba postback
        ↓
Everflow
        ↓
Affiliate 12345 gets credited

Ringba can also use dynamic number pools, so the affiliate/source can be associated with the caller even when the consumer doesn't click immediately before calling. support.ringba.com

Invoca is the other serious option

Invoca is particularly strong if you care about whether the call actually converted, rather than merely whether someone called. It can analyze call outcomes and supports pay-per-call programs where commissions can depend on call duration, geography, timing, or actual sales/conversion outcomes. www.invoca.com

Invoca also has a direct Everflow integration that synchronizes offers and affiliate data and pulls call tracking data into Everflow. helpdesk.everflow.io

If you're already using Impact, Invoca has a specific integration that lets phone-call conversions count toward affiliate/partner commissions. www.invoca.com

What I'd choose

If you're primarily an affiliate/performance marketing operation:
Everflow + Ringba.

If you're an enterprise advertiser and call quality/conversation intelligence matters:
Everflow + Invoca.

If you need a simple call-tracking system rather than a full affiliate network:
Look at CallRail, but I'd be less inclined to use it as the core of a sophisticated affiliate payout system.

The key question is how the affiliate is driving the call. If it's:

1. Affiliate → landing page → consumer calls — dynamic number insertion + affiliate click ID is ideal.
2. Affiliate publishes a unique phone number — unique-number attribution is simpler.
3. Affiliate → direct-to-phone call — you want clickless/call-based conversion tracking.
4. You pay only for qualified calls/sales — Ringba/Invoca + Everflow becomes particularly compelling.

If you tell me your current affiliate platform (Everflow, Impact, TUNE, PartnerStack, custom, etc.) and whether affiliates send traffic to a website or directly to phone numbers, I can recommend the exact setup and data flow.

Yes. If your goal is “affiliate sends visitor → affiliate ID is preserved → visitor calls → call becomes a conversion attributed to that affiliate”, there are several good options.

Best fits

1. Phonexa — probably the closest match to what you're describing.
Its Call Logic product is specifically designed for affiliate/pay-per-call campaigns. It supports publisher/affiliate-level tracking, source IDs, call routing, and server-to-server postbacks when a call becomes a billable/conversion event. Phonexa explicitly supports passing an affiliate source/subID into the tracking system. phonexa.com

Phonexa Call Logic

2. Invoca — strongest if you're an advertiser rather than an affiliate network.
Invoca has a specific pay-per-call solution and documents tracking phone leads from affiliate partnerships. It can attribute calls to individual affiliate partners and integrate with affiliate/performance-marketing platforms. www.invoca.com

Invoca Pay-Per-Call

3. CallTrackingMetrics — flexible and potentially easier to customize.
It uses Dynamic Number Insertion (DNI) to associate a caller with the source that brought them to the site. You could pass an affiliate ID as a URL/source parameter and use that attribution on the resulting call. calltrackingmetrics.zendesk.com

CallTrackingMetrics

The architecture I'd recommend

If your affiliate links look like:

https://yoursite.com/?affiliate_id=12345&subid=abc789

you want the system to maintain that ID through the funnel:

Affiliate
   ↓
affiliate_id=12345
   ↓
Landing page
   ↓
Tracking system stores affiliate_id
   ↓
Unique tracking phone number
   ↓
Customer calls
   ↓
Call qualifies (e.g. ≥90 sec / answered / sale)
   ↓
Conversion attributed to affiliate 12345
   ↓
S2S postback → affiliate platform

The S2S postback piece is particularly important if you're paying affiliates for qualified calls rather than merely wanting analytics. Phonexa explicitly supports sending conversion data back to an affiliate network/CRM after the call outcome is determined. phonexa.com

My shortlist

• Running an affiliate network / pay-per-call marketplace: Phonexa
• You are the advertiser with lots of affiliate partners: Invoca
• You want a highly configurable call-tracking system: CallTrackingMetrics
• You want something simpler: WhatConverts — its tracking system supports dynamic numbers tied to marketing sources. www.whatconverts.com

If you tell me what affiliate platform you're using (Impact, Everflow, TUNE, CAKE, HasOffers, custom, etc.) and whether the conversion is “answered call,” “90+ second call,” or an actual sale, I can narrow this down to the 2–3 setups that will work technically, including how the affiliate ID gets passed into the call and back as a conversion.

Yes. If the goal is “affiliate sends a visitor → visitor calls a phone number → we know which affiliate generated the call → only count qualified calls as conversions,” there are several good options.

Best fits

Phonexa is probably the closest match if you're actually operating an affiliate program/network. Its call-tracking product supports publisher/affiliate-level reporting, source-level attribution, call qualification, and server-to-server postbacks when a call reaches a qualifying outcome. phonexa.com

Ringba is also particularly well suited to pay-per-call. It has explicit concepts for publishers, campaigns, tracking numbers, and attributing traffic sources to calls. support.ringba.comphonexa.com

Invoca is stronger if you're primarily an advertiser wanting sophisticated marketing attribution rather than running the affiliate infrastructure itself. It supports phone conversion attribution and reporting completed conversions back through its API. www.invoca.com

How I'd implement it

For example, your affiliate link could contain:

https://yoursite.com/offer?affiliate_id=12345&sub_id=abc789

The tracking system stores affiliate_id=12345 in the visitor/session. A dynamic tracking number is then displayed to that visitor. When they call:

Affiliate 12345
    ↓
Landing page
    ↓
Dynamic phone number
    ↓
Inbound call
    ↓
Call tracking platform
    ↓
Qualified call? (>90 seconds, answered, sale, etc.)
    ↓
Conversion attributed to Affiliate 12345
    ↓
S2S postback → affiliate platform

That last step is important if you're paying affiliates for calls. You don't merely want to count calls—you want the call platform to send something like:

affiliate_id=12345
sub_id=abc789
conversion=1
call_id=987654
payout=50.00

back to your affiliate platform.

My first choice would be Phonexa or Ringba if affiliate ID → phone call → qualified conversion → affiliate payout is the core workflow. Phonexa specifically advertises server-to-server postbacks and affiliate/publisher-level call reporting, while Ringba is heavily oriented toward pay-per-call networks. support.ringba.comphonexa.com

If you tell me what affiliate software you're currently using (Everflow, Impact, Tune, PartnerStack, CAKE, HasOffers/Trackier, custom, etc.) and whether affiliates send web traffic, calls, or both, I can narrow this down to the 2–3 integrations that would require the least custom development.

Yes. If the goal is “affiliate sends traffic → visitor calls a phone number → we attribute the call/conversion back to affiliate ID”, there are several good options. The strongest choices are:

1. Ringba — probably the best match

Ringba is specifically built around performance marketing and pay-per-call. It supports publishers/affiliates, tracking numbers, call attribution, routing, and reporting. www.ringba.com

You can pass an affiliate identifier in the incoming traffic URL, for example:

yoursite.com/offer?aff_id=12345

Then use Ringba's tracking/number-pool functionality to associate the visitor and resulting call with that traffic source. Ringba's tracking tags support dynamic number insertion and associate landing-page/session information with call data. support.ringba.com

I'd start here if you're running a traditional affiliate program.

2. Invoca — very strong for enterprise

Invoca is another particularly good fit. Its RingPool API explicitly supports allocating tracking numbers on behalf of affiliates and passing an affiliate ID in the API request. www.ringba.comdevelopers.invoca.net

For example, Invoca documents the concept of:

...?pid=5567

where pid represents the affiliate/publisher ID. The resulting tracking number can then be associated with that affiliate's call. www.ringba.comdevelopers.invoca.net

It also supports conversion reporting, so you can go beyond “a call happened” and report a downstream conversion/order back into the platform. developers.invoca.net

3. Phonexa — worth considering if you're essentially building a pay-per-call network

Phonexa has an especially strong affiliate-network orientation. Its Call Logic product tracks calls at the publisher/affiliate level and supports server-to-server postbacks when a call meets your conversion criteria. phonexa.com

This is attractive if you need things like:

• affiliate IDs
• publisher payouts
• call duration qualification
• buyer payouts
• call routing
• caps
• duplicate-call detection
• conversion/postback reporting
• affiliate and buyer reporting

Phonexa specifically positions its software for affiliate networks, advertisers, publishers, and pay-per-call businesses. phonexa.com

What I'd recommend

If your architecture is:

Affiliate → affiliate link → landing page → phone call → qualified call/sale → affiliate commission

I'd shortlist them as:

1. Ringba — best purpose-built choice for a performance-marketing/pay-per-call setup.
2. Phonexa — best if you need a more complete affiliate-network/pay-per-call infrastructure.
3. Invoca — best if you're an enterprise advertiser and want sophisticated attribution/conversion intelligence.

The key technical requirement I'd insist on is persistent affiliate-ID propagation, not merely assigning each affiliate a static phone number. Ideally you pass something like aff_id, sub_id, and campaign ID into the tracking platform, preserve those through the landing-page session, and then have the platform fire an S2S conversion/postback when the call qualifies.

If you tell me whether you're the advertiser/merchant or the affiliate network, and roughly how many affiliates/calls per month, I can narrow this to the best 2–3 options and show you exactly how the affiliate ID → phone call → conversion flow would work.

Yes. If the goal is specifically “affiliate ID → phone call → qualified/converting call → affiliate payout”, there are a few strong options.

Best fit: Ringba + Everflow

Ringba + Everflow is probably the cleanest architecture for a performance/affiliate program.

• Everflow holds the affiliate/partner ID, offer, conversion, and payout.
• Ringba handles the phone numbers, call routing, call recording, IVR, duration/quality rules, and call conversion.
• Ringba can map the Everflow affiliate ID to the Ringba publisher's Sub ID.
• When a call converts, Ringba sends a server postback containing the affiliate ID and conversion value back to Everflow. helpdesk.everflow.iohelpdesk.everflow.io
• You can also use dynamic number pools if affiliates send traffic to your landing page, or dedicated numbers if each affiliate gets a phone number. helpdesk.everflow.io

This is particularly good if you're running pay-per-call affiliate campaigns.

Everflow Pay-Per-Call Integrations
Ringba + Everflow integration documentation

Another strong option: Invoca + Everflow

Invoca is more enterprise-oriented and has sophisticated call attribution/conversation analytics.

Everflow has a native Invoca integration that synchronizes offers and affiliate data and brings call/revenue data into Everflow. Reporting is updated approximately every five minutes. helpdesk.everflow.io

Invoca specifically supports affiliate/pay-per-call use cases and attribution of phone leads back to affiliate partners. www.invoca.com

Invoca call tracking

The key capability to look for

You want a system that supports clickless conversion tracking as well as normal click-based attribution.

For example:

Affiliate → Affiliate ID 123 → phone number → call → qualified call → conversion → postback → Affiliate 123 gets credit

That's important because a phone call may happen without a tracking-link click immediately preceding the conversion. Everflow explicitly supports clickless conversions using offer_id + affiliate_id/oid + affid. helpdesk.everflow.iohelpdesk.everflow.io

My recommendation

If you tell me how your affiliates generate the calls (e.g. landing-page traffic, each affiliate gets a unique phone number, Google Ads on behalf of affiliates, direct-dial campaigns, etc.), I can recommend the exact tracking architecture and explain how the affiliate ID should flow from click → phone number → call → conversion → payout.

Yes. If the requirement is specifically “affiliate sends traffic → caller phones us → we attribute the call/conversion back to the affiliate ID”, there are several good options.

Best fits

I'd look hardest at Phonexa or Ringba

Phonexa is particularly well aligned if you're actually operating an affiliate program/network. Its platform explicitly supports tracking calls at the affiliate/publisher level, and it has server-to-server postbacks so conversion information can be sent back to the affiliate network. It also supports call distribution, buyer payouts, publisher payouts, and pay-per-call workflows. phonexa.com

Invoca is stronger if you're primarily an advertiser/brand wanting sophisticated marketing attribution. It can attribute phone leads to specific affiliate partnerships and provides granular attribution across the customer journey. www.invoca.com

The architecture I'd recommend

For example, an affiliate link could look conceptually like:

yoursite.com/offer?aff_id=12345&sub_id=abc789

Then:

1. Affiliate sends visitor to your landing page.
2. Your tracking system captures aff_id=12345.
3. Visitor sees a dynamic tracking phone number associated with that affiliate/session.
4. They call.
5. Call platform records the call against aff_id=12345.
6. You determine whether the call is a conversion — e.g. 120+ seconds, qualified lead, sale, appointment, etc.
7. Platform fires an S2S postback to your affiliate platform:

affiliate_id=12345 → conversion=true → payout=$XX

That last step is important. You don't just want call tracking—you want call outcome → affiliate conversion postback.

One important distinction

If you tell me what your affiliate software/network is (e.g. Tune, Everflow, Impact, CAKE, HasOffers/Trackier, custom affiliate platform) and whether you're the advertiser receiving the calls or the affiliate network, I can narrow this down considerably and tell you which platforms can pass the affiliate ID through the call and fire the conversion back automatically.

Yes. If the requirement is specifically “affiliate clicks → affiliate ID → phone call → qualified/converted call”, I’d look at these first:

My top two

1. Invoca — probably the strongest match

Invoca is particularly well suited if you're operating an affiliate program or pay-per-call setup. Its transaction API actually has fields for affiliate_id and affiliate_id_from_network, so the affiliate identifier can remain attached to the call transaction. developers.invoca.net

It also supports pay-per-call programs where you can define what constitutes a commissionable call based on things like duration, geography, time, and call outcome. www.invoca.com

Invoca

2. Ringba — especially if this is an affiliate/pay-per-call network

Ringba is worth serious consideration if you're essentially running:

Affiliate → tracking link → landing page/phone number → call → buyer → conversion/payout

It's designed around call monetization and pay-per-call traffic rather than merely adding phone attribution to conventional PPC campaigns. Current comparisons also specifically identify Ringba as a strong choice for pay-per-call networks. taqtics.com

Ringba

What I'd implement

The architecture I'd recommend is:

Affiliate
   ↓
Tracking URL
?affiliate_id=12345
&sub_id=abc789
   ↓
Landing page
   ↓
Tracking platform stores affiliate_id
   ↓
Dynamic phone number / call routing
   ↓
Inbound call
   ↓
Call ID + affiliate_id
   ↓
Qualification rules
   ↓
"Converted" event
   ↓
Postback/API → affiliate platform

The important part is not just tracking which number was called. You want the affiliate ID persisted as a first-class parameter through the entire customer journey, so you can ultimately say:

Affiliate 12345 generated 87 calls, 52 qualified calls, 31 sales, $X revenue.

Invoca is particularly compelling here because its transaction data explicitly includes the affiliate identifiers. developers.invoca.net

If you tell me what affiliate software you're using (Impact, PartnerStack, Everflow, TUNE, CAKE, HasOffers/NETwork, custom, etc.) and whether the affiliates send users to a website or directly to phone numbers, I can narrow this down to the best 2–3 options and show you exactly how I'd pass the affiliate ID through to the call conversion.

Yes. If your requirement is specifically “affiliate sends traffic → affiliate ID is preserved → visitor calls → call is qualified as a conversion → conversion is attributed back to that affiliate ID”, you want a performance/pay-per-call tracking platform, rather than just a generic call tracker.

Best options

My first two would be Invoca and Ringba.

Invoca is particularly well suited if you're actually running an affiliate/pay-per-call program. It explicitly supports advertisers, publishers, networks and agencies, including managing partners, campaigns and payouts. It can assign unique numbers to publishers/campaigns and determine whether a call qualifies for commission based on things like duration, geography, time and call outcome. www.invoca.comwww.invoca.com

Invoca — Pay-per-call tracking

The setup you'd want

For example, your affiliate link could look conceptually like:

https://yoursite.com/offer?affiliate_id=12345

The tracking system stores:

affiliate_id = 12345
click_id = abc789
landing_page = /offer

The visitor then sees a dynamically assigned tracking number:

(800) 555-1234

When they call, the call record retains:

affiliate_id: 12345
click_id: abc789
caller: +1...
duration: 8:42
qualified: yes
conversion: yes
payout: $75

You can then send the conversion back to the affiliate platform/network using an API or postback.

If you're an affiliate network

I'd lean heavily toward Invoca or Ringba, because you probably need more than "which marketing campaign generated this call." You likely need:

• Affiliate/sub-ID tracking
• Unique tracking numbers
• Dynamic number insertion
• Call routing
• Call recording/transcription
• Minimum-duration rules
• Conversion/qualified-call rules
• Duplicate/fraud filtering
• Real-time conversion events
• Affiliate payouts
• API/postbacks
• Buyer/advertiser routing
• Reporting by affiliate → campaign → call → conversion

Invoca specifically describes its platform as an independent source of truth for affiliates and advertisers and supports partner/campaign/payout management. www.invoca.comwww.invoca.com

WhatConverts is a cheaper/easier alternative if you're primarily an advertiser wanting to attribute calls to marketing sources. Its current plans include call tracking, dynamic number insertion, call recording, marketing data attached to calls and API access. www.whatconverts.com

WhatConverts

If you tell me whether you're the affiliate network, the advertiser receiving the calls, or the affiliate, plus what your affiliate software is (e.g. Everflow, TUNE, Impact, PartnerStack, HasOffers/CAKE), I can narrow this down to the 2–3 platforms that can actually pass the affiliate ID through and fire the conversion/postback automatically.

Yes. If the requirement is specifically “affiliate clicks/traffic → phone call → qualified/converted call → credit that conversion to the affiliate ID”, there are several good options. The strongest fits are Ringba + Everflow, Invoca + Everflow, and TrackDrive + Everflow.

My first choice: Ringba + Everflow

This is probably the architecture I'd look at first if you're running an affiliate program and paying affiliates for phone conversions.

Everflow's documented Ringba integration specifically supports mapping:

Everflow Affiliate ID → Ringba Publisher/Sub ID → phone call → conversion → Everflow postback

Their documentation shows the affiliate ID being placed into Ringba's publisher Sub ID, while the Everflow Offer ID is mapped to the Ringba campaign. When the call converts, Ringba sends the Affiliate ID and Offer ID back to Everflow via a server postback. helpdesk.everflow.io

So you can effectively have:

Affiliate 123
     ↓
Affiliate tracking URL
     ↓
Landing page / phone number
     ↓
Ringba tracking number
     ↓
Incoming call
     ↓
Qualified / converted call
     ↓
Ringba postback
     ↓
Everflow Affiliate ID = 123
     ↓
Affiliate gets $X payout

That's much closer to an actual affiliate/pay-per-call platform than something like basic call tracking.

TrackDrive is another very good fit

TrackDrive has an explicit concept of Traffic Sources, where affiliates/publishers are represented by an afid (affiliate ID). It associates the traffic source with incoming calls and uses that attribution for payout calculations and reporting. support.trackdrive.com

It also has a documented Everflow integration, including matching TrackDrive Traffic Source IDs with Everflow affiliate IDs. helpdesk.everflow.io

Invoca is the enterprise option

Invoca is substantially more sophisticated if you're dealing with large call volumes, multiple acquisition channels, call qualification, revenue attribution, and detailed conversation analytics.

Invoca explicitly supports pay-per-call programs, including partner management, campaigns, payouts, and independent verification of calls. www.invoca.com

It also has an Everflow integration specifically for synchronizing offer and affiliate data and bringing call-tracking data into Everflow. helpdesk.everflow.io

What I'd choose

If your situation is:

“We have affiliates sending us leads, those leads call our business, and we want to pay the affiliate when the call meets criteria X.”

I'd shortlist:

1. Ringba + Everflow — best overall for this use case
2. TrackDrive + Everflow — very strong alternative
3. Invoca + Everflow — best if you're enterprise-scale / need sophisticated call analytics

The important distinction is that CallRail-style software is primarily marketing call attribution, whereas Ringba/TrackDrive + an affiliate platform are designed around the publisher → call → payout workflow.

If you tell me how your affiliate traffic works (e.g. affiliate link → landing page → user calls, or affiliate is directly buying PPC and forwarding calls), I can recommend the exact tracking architecture and explain how the affiliate ID survives from the click all the way through the phone call.

Yes. If the requirement is “affiliate sends a click with an affiliate ID → user calls a phone number → we attribute the call/conversion back to that affiliate ID → optionally send the conversion/payout back to the affiliate platform,” there are several good options.

Best fits

My first two choices: Ringba or TrackDrive

Ringba is particularly well suited if you're operating an affiliate/pay-per-call model. It supports campaign tracking, call attribution, URL parameters, traffic-source attribution, partner management, routing, and APIs. www.ringba.com

Ringba

TrackDrive is also very strong for this exact architecture. Its concept of a Traffic Source maps naturally to an affiliate/publisher, and it explicitly supports an afid (affiliate ID). The attributed source is stored against the call/lead and can be used for payout calculations, caps, and reporting. support.trackdrive.com

TrackDrive

TrackDrive also has documented integrations with Ringba, including passing call/lead data between the systems and postbacks. support.trackdrive.com

A typical setup

For example, your affiliate link could look conceptually like:

yourdomain.com/offer?afid=12345&subid=abc789

You preserve afid=12345 when the visitor lands on your site. Your call-tracking system then associates the visitor/call with that affiliate, using either:

1. Dynamic number insertion (DNI) — visitor sees a tracking number associated with their affiliate/session.
2. Dedicated numbers — each affiliate/campaign gets its own number.
3. URL/session parameters — affiliate ID is retained and associated with the tracking session/call.

When the call happens:

Affiliate 12345 → tracking number → call → qualified/converted → conversion recorded against affiliate 12345 → postback to affiliate platform

That last step is important if you're paying affiliates on qualified calls, booked appointments, sales, duration, etc.

If you're already using an affiliate platform

The choice gets more specific. For example, if you're using Everflow, TUNE, Impact, PartnerStack, CAKE, or another affiliate platform, I'd choose the call tracker based on its postback/API capabilities rather than just call-recording features.

Invoca explicitly positions its pay-per-call product around managing partners/affiliates and integrating with performance-marketing platforms. www.invoca.com

Invoca

If you tell me which affiliate platform you're using (e.g. Everflow, Impact, TUNE, CAKE, custom), and whether the affiliate sends traffic to a website or directly calls a number, I can map out the exact tracking architecture and recommend the best 2–3 options.

Yes. If the requirement is specifically “affiliate clicks/IDs → phone call → qualified/converted call → affiliate payout”, there are several good options, but they differ substantially.

Best fits

My first choice would be Ringba + Everflow. Everflow explicitly supports clickless conversion tracking for phone calls, including passing an affiliate_id, and has a documented Ringba integration. helpdesk.everflow.io

The basic flow would be:

Affiliate
   ↓
Affiliate tracking link
   ↓
affiliate_id / sub_id
   ↓
Landing page or tracking phone number
   ↓
Ringba
   ↓
Phone call
   ↓
Qualified/converted call
   ↓
S2S postback
   ↓
Everflow
   ↓
Affiliate gets credited

Ringba can attribute calls to traffic sources and other tracking data, while Everflow handles the affiliate/partner side. www.ringba.comsupport.ringba.com

An important detail

You don't necessarily need a click ID to attribute a phone call.

For example, Everflow documents a clickless conversion setup specifically for situations where someone gets a phone number directly and calls. You can map:

• Offer ID → Ringba campaign
• Affiliate ID → Ringba publisher/sub-ID
• Call conversion → Ringba
• Conversion + affiliate ID → Everflow via server postback

That means you can credit Affiliate 123 with a $50 qualified call even if there isn't a traditional browser click immediately preceding the call. helpdesk.everflow.io

Invoca is the other serious option

Invoca is more enterprise-oriented and has sophisticated call attribution, including partner/affiliate attribution and pay-per-call functionality. It also has a direct Everflow integration for synchronizing offer and affiliate data and importing call tracking data. www.invoca.com

So I'd roughly choose:

Ringba + Everflow → if you're building/managing an affiliate or pay-per-call program.

Invoca + Everflow → if you're an enterprise advertiser with complex call-center attribution and a larger budget.

Ringba + Voluum → if you're primarily an affiliate/media buyer and already use Voluum. Ringba has a documented integration that sends inbound calls as conversions to Voluum. support.ringba.com

If you tell me how your affiliates send traffic (unique URLs, coupon codes, dedicated phone numbers, etc.) and whether you're paying per call, per qualified call, or per sale, I can map out the exact tracking architecture and recommend the simplest stack.

Yes. If the goal is “affiliate clicks → affiliate ID → phone call → qualified/converted call → commission”, you want a platform that can preserve an affiliate/subID through the click and attach it to the resulting call.

Best fits

My first choice for an affiliate program would be Ringba. It was specifically built around performance marketing and pay-per-call, with partner management, call routing, campaign tracking, URL parameters, attribution, webhooks/API, and real-time reporting. www.ringba.com

Invoca is the other serious option if you're an enterprise advertiser/network. It explicitly supports pay-per-call programs and managing partners, campaigns, payouts, and call-conversion data. www.invoca.com

How I'd structure it

For example, your affiliate sends:

https://yourdomain.com/offer?affiliate_id=12345&sub_id=abc789

Your tracking system stores:

affiliate_id = 12345
sub_id       = abc789

The visitor then calls a dynamically assigned tracking number. The call record retains the affiliate/sub ID:

Affiliate 12345
   ↓
Click
   ↓
Landing page
   ↓
Tracking number
   ↓
Phone call
   ↓
Call qualified = YES
   ↓
Conversion
   ↓
Commission = $75

You can then send the conversion back to the affiliate platform via postback/webhook/API, so the affiliate gets credited just as they would for an online conversion.

One important distinction

If you're running an affiliate program where many affiliates send traffic to your website, I'd lean Ringba + your affiliate platform.

If you're a pay-per-call network that actually buys/sells calls and needs routing, buyers, sellers, caps, payouts, and call qualification, Ringba or Invoca becomes much more compelling. Ringba specifically advertises automated partner management, routing/capping/financial rules, and pay-per-call functionality. www.ringba.com

If you tell me what affiliate software you're currently using (Impact, Everflow, TUNE, CAKE, PartnerStack, custom, etc.) and whether the conversion is “any call,” “call > X minutes,” or “sale made during the call,” I can map out the exact setup and recommend the best combination.

Yes. If your requirement is specifically “affiliate clicks → unique tracking context/affiliate ID → phone call → qualified/conversion event → affiliate payout/postback,” there are a few platforms that are much better suited than generic call-tracking tools.

Best fits

My first choice for an affiliate-heavy operation would be Phonexa. Its call-tracking product explicitly supports an affiliate view, publisher-level metrics, billable call duration, and server-to-server postbacks to an affiliate network/CRM after a call's outcome is determined. phonexa.com

Invoca is another strong option, particularly if you're operating at enterprise scale. Its pay-per-call product is designed around networks, publishers, advertisers and payouts, and it supports integrations with affiliate/performance-marketing platforms including CJ and TUNE. www.invoca.comphonexa.com

The architecture I'd recommend

For example, an affiliate sends someone to:

https://yourdomain.com/offer?aff_id=12345

Your tracking system stores:

aff_id = 12345
click_id = abc789

The visitor gets a dynamically assigned phone number:

1-800-555-1234

When they call:

Call
 ↓
Tracking platform identifies affiliate/click
 ↓
Call is routed to your sales team/buyer
 ↓
Call meets conversion criteria
   (e.g. ≥ 90 seconds, answered, sale made)
 ↓
Conversion recorded against aff_id=12345
 ↓
S2S postback to affiliate platform
 ↓
Affiliate gets credited

The important part is not simply having a tracking number. You want the platform to preserve the affiliate/click ID through the call and then fire a server-side conversion/postback. Phonexa explicitly supports this workflow. phonexa.com

One important distinction

If you're an advertiser with a handful of affiliates, I'd look at Retreaver / Invoca / CallTrackingMetrics.

If you're running an affiliate network or pay-per-call marketplace, I'd put Phonexa and Invoca at the top of the list because they are designed around publishers, buyers, call distribution, qualification, and payouts—not just marketing call analytics. www.invoca.comphonexa.com

If you tell me what affiliate software/network you're currently using (e.g. Everflow, TUNE, Impact, CAKE, HasOffers/Trackdesk, custom, etc.), I can narrow this down to the 2–3 systems that can actually pass your affiliate ID through to a phone conversion and fire the conversion back automatically.

Yes. For affiliate-driven phone conversions, you usually want a call tracking + affiliate attribution platform, not just a basic marketing call tracker. The key features to look for are:

• Affiliate ID / publisher ID passed into the tracking URL
• Unique tracking numbers or dynamic number insertion (DNI)
• Call-level attribution (who generated the call)
• Conversion rules (e.g., answered > 90 seconds, qualified lead, sale)
• S2S postbacks/API to send conversions back to your affiliate platform
• Fraud detection and duplicate call handling

Good options:

Typical affiliate call tracking setup

1. Affiliate sends traffic:

yourdomain.com/?aff_id=12345&sub_id=abc

2. Tracking platform stores:

Affiliate ID: 12345
Sub ID: abc
Campaign: Auto Insurance
Landing page: /quote

3. Visitor sees a unique phone number.

4. Customer calls.

5. Platform records:

Call ID: 987654
Affiliate: 12345
Duration: 4:32
Qualified: Yes
Payout: $35

6. Platform sends a conversion back:

POST /affiliate/postback?
aff_id=12345&
conversion_id=987654&
payout=35

My shortlist by use case

• Running a true affiliate/pay-per-call program: Phonexa or Ringba
• You have many affiliates and need routing/buyer management: Ringba or Phonexa
• You are an advertiser buying affiliate traffic: Invoca or CallTrackingMetrics
• You only need basic affiliate source attribution: CallRail may be enough

If you already use an affiliate platform such as Everflow, Impact.com, TUNE, or CAKE by Accelerize, the best choice depends on whether you need the call tracker to be the affiliate system of record or just send call conversions back into it.

If your goal is to attribute phone calls to individual affiliates, you need a platform that combines:

• Dynamic phone number insertion (DNI)
• Affiliate click tracking (via affiliate ID, subID, click ID, etc.)
• Call attribution back to the affiliate
• API or webhook integrations with your affiliate platform and CRM

Here are some of the strongest options:

Top recommendations

1. Ringba

Probably the most popular in the affiliate/pay-per-call world.

Pros:

• Tracks affiliate IDs, sub IDs, click IDs
• Pools of tracking numbers
• Real-time reporting
• Fraud detection
• Payout calculations
• APIs and webhooks
• Designed specifically for pay-per-call campaigns

Best if you're paying affiliates based on qualified calls.

2. Retreaver

Another platform built around affiliate and performance marketing.

Features:

• URL parameter tracking
• Session attribution
• Dynamic number replacement
• Affiliate routing
• Call qualification rules
• Conversion events
• CRM integrations

Many affiliate networks use Retreaver.

3. CallRail

If your affiliate program isn't extremely large.

Typical flow:

Affiliate sends:

https://example.com/?affiliate_id=12345

CallRail stores:

• affiliate_id
• utm_source
• gclid
• landing page
• visitor session

When the visitor calls:

Call
   ↓
Tracking Number
   ↓
Conversion
   ↓
affiliate_id = 12345

Very easy to set up.

4. CallTrackingMetrics

Excellent if you need:

• calls
• forms
• chats
• SMS
• CRM syncing

Can attribute everything back to URL parameters like:

affiliate_id
partner
subid
clickid
offer
campaign

5. Invoca

More enterprise-focused.

Good if you have:

• thousands of calls/day
• Salesforce
• enterprise affiliate programs
• AI conversation scoring
• revenue attribution

Usually more expensive.

How attribution typically works

An affiliate sends traffic such as:

example.com/?aff_id=812&subid=facebook_ad3

The tracking software:

1. Reads the URL parameters.
2. Stores them in the visitor session.
3. Displays a unique tracking phone number.
4. When the visitor calls, the software associates the call with:
   • Affiliate ID
   • Sub ID
   • Campaign
   • Landing page
   • Keyword (if applicable)
   • Revenue or qualified-call status

The resulting record might look like:

Call ID: 98273
Affiliate: 812
Sub ID: facebook_ad3
Duration: 7m 42s
Qualified: Yes
Sale Amount: $420
Commission: $84

If you're running your own affiliate software

Most call-tracking platforms can capture custom URL parameters, including:

• affiliate_id
• affiliate
• partner_id
• subid
• subid1
• subid2
• clickid
• transaction_id

This makes them compatible with many affiliate systems without requiring a native integration.

Recommendation by scale

• Small to medium affiliate program (up to ~100 affiliates): CallRail or CallTrackingMetrics.
• Affiliate network or pay-per-call business: Ringba or Retreaver.
• Enterprise with high call volume and advanced analytics: Invoca.
• All-in-one performance marketing platform (affiliate management plus call tracking): Phonexa.

If you can share:

• approximately how many affiliates you have,
• expected monthly call volume,
• whether you already use an affiliate platform (e.g., Post Affiliate Pro, Everflow, Impact, PartnerStack, Tune/HasOffers, or a custom solution),
• and whether commissions are based on every call or only qualified/sales calls,

I can narrow the list to the best fit and outline the integration approach.

If your goal is to attribute phone call conversions back to individual affiliates, you'll want a platform that combines dynamic call tracking with affiliate parameter capture (such as affiliate_id, subid, click_id, or UTM parameters).

The best options depend on your affiliate platform and call volume.

1. CallRail

Good if you're already running web-based affiliate traffic.

How it works:

• Affiliate sends traffic to:

  yoursite.com/?affiliate_id=12345

• CallRail reads the URL parameter.
• Visitor sees a unique tracking number.
• If they call:
  • affiliate_id
  • landing page
  • campaign
  • keyword
  • UTMs

are stored with the call.

Pros:

• Easy setup
• Good reporting
• Affordable
• Zapier support

2. Ringba (one of the strongest choices)

Ringba was designed around pay-per-call marketing.

Features:

• Per-affiliate routing
• Track publisher IDs
• Pass click IDs
• IVR
• Real-time payouts
• Fraud detection
• Call quality scoring

If affiliates are primarily driving phone calls, Ringba is often one of the strongest fits.

3. Retreaver

Very popular with lead generation companies.

Supports:

• affiliate_id
• publisher_id
• subid
• clickid
• Google Click ID (GCLID)
• Meta Click ID (FBCLID)

You can trigger conversions only after:

• minimum call duration
• qualified caller
• sales outcome
• custom webhook

4. Invoca

Enterprise-level solution.

Useful if you have:

• multiple brands
• thousands of calls
• call centers
• Salesforce
• Adobe
• enterprise analytics

It can attribute revenue back to affiliates and campaigns.

5. CallTrackingMetrics

Very flexible.

Supports:

• Dynamic Number Insertion (DNI)
• URL parameter capture
• Custom fields
• API
• Call scoring
• CRM sync

Works well when you need marketing attribution across affiliates, paid search, and organic traffic.

Typical implementation

1. Affiliate link:

https://example.com/?affiliate_id=8472

2. Visitor lands.

3. Call tracking script:
4. saves affiliate_id
5. assigns a tracking number

4. Visitor calls.

5. Call record contains:

Affiliate: 8472
Campaign: Summer2026
Landing Page: /insurance
Duration: 11m 42s
Recording: Yes
Qualified: Yes
Sale Amount: $850

6. The call tracking platform sends the conversion to:
7. Affiliate platform
8. CRM
9. Reporting dashboard
10. Billing system

If you're using an affiliate platform

Many affiliate platforms can work with these call tracking systems through APIs, webhooks, or automation. Examples include:

• Everflow
• Trackdesk
• Post Affiliate Pro
• TUNE
• Impact.com

The affiliate platform passes a unique click or affiliate identifier to your site, and the call tracking platform stores that identifier with the call. When a call qualifies as a conversion, the tracking platform can send the conversion back so the correct affiliate receives credit.

My recommendation by use case

• Small to midsize business: CallRail for ease of setup and solid attribution.
• Affiliate-heavy lead generation or pay-per-call: Ringba or Retreaver, as they're designed specifically for affiliate and publisher attribution.
• Enterprise marketing teams: Invoca for advanced attribution and analytics.
• Agencies or businesses needing broad marketing attribution: CallTrackingMetrics.

If you can share:

• your affiliate software (e.g. Everflow, Impact, Trackdesk, TUNE, custom),
• your phone provider (Twilio, RingCentral, etc.), and
• whether affiliates send traffic to your website or directly to a phone number,

I can recommend the simplest integration architecture for your setup.

If you want to attribute phone call conversions back to individual affiliates, you generally need three capabilities working together:

1. Dynamic call tracking (unique phone numbers shown to visitors)
2. Affiliate click tracking (affiliate ID, subID, click ID)
3. Passing the affiliate identifier into the call record so the conversion can be attributed.

There are several platforms that support this well.

How it usually works

An affiliate sends traffic like:

https://example.com/?aff_id=247&subid=facebook_ad1

The call tracking software:

• stores aff_id=247
• stores the subID/click ID
• swaps the displayed phone number with a unique tracking number
• when the visitor calls, the software associates the call with:
  • affiliate 247
  • campaign
  • landing page
  • keywords (if applicable)
  • revenue
  • recording

Then you can pay commissions based on completed calls.

If you already have an affiliate platform

Many affiliate systems don't do call tracking themselves, but they integrate well.

Examples include:

• Everflow
• TUNE
• Impact.com
• Post Affiliate Pro

A common setup is:

Affiliate
      ↓
Affiliate software
      ↓
Landing page (?aff_id=247)
      ↓
Call tracking platform
      ↓
Phone call
      ↓
Conversion
      ↓
Webhook/API back to affiliate software

Best choices by use case

• General affiliate program: CallRail or CallTrackingMetrics
• High-volume pay-per-call: Ringba or Retreaver
• Enterprise with Salesforce/HubSpot: Invoca
• Lead generation company: Phonexa
• Need to pay affiliates based on qualified calls: Ringba is particularly strong because it was designed around affiliate and pay-per-call workflows.

If you're handling hundreds or thousands of affiliate calls per month, Ringba and Retreaver are typically the strongest options because they support:

• affiliate IDs and subIDs
• real-time call routing
• payout rules
• fraud detection
• postback/webhook integrations
• buyer routing
• detailed reporting by affiliate and campaign

If you can share which affiliate platform you're using (for example, Everflow, Impact, TUNE, Post Affiliate Pro, Rewardful, or a custom system), I can recommend the simplest integration and outline the data flow.

If you want to attribute phone call conversions back to individual affiliates, you need software that combines call tracking with dynamic phone numbers and the ability to pass an affiliate ID (or click ID) through the visitor journey.

The best options depend on whether you're running your own affiliate program or using an affiliate network.

How it typically works

1. Affiliate sends traffic to:

   yoursite.com/?affid=12345

or

   ?affiliate_id=12345

2. The call tracking software:
   • Stores the affiliate ID in a cookie/session.
   • Replaces the phone number on the website with a tracking number (Dynamic Number Insertion).
   • When the visitor calls, it associates that tracking number with the stored affiliate ID.
   • The call is logged as:

     Affiliate 12345
        ↓
     Visitor
        ↓
     Phone Call
        ↓
     Qualified Call
        ↓
     Sale

3. The platform can then:
   • report calls by affiliate
   • report revenue by affiliate
   • send conversions back to your affiliate platform via API or postback

If you're already using an affiliate platform

Many affiliate systems can receive phone conversions:

• Everflow
• Trackier
• TUNE
• Impact.com

These are commonly integrated with Ringba, CallTrackingMetrics, Invoca, or CallRail so phone conversions appear alongside online conversions.

If you're running a pay-per-call affiliate program

The industry standards are:

1. Ringba
2. Retreaver
3. Phonexa

They support:

• affiliate IDs
• sub IDs (SubID, ClickID, etc.)
• IVR routing
• call qualification (minimum duration)
• payouts by affiliate
• fraud detection
• API/webhooks

If you're only tracking calls from your own website

A simpler setup is often enough:

• CallRail
• CallTrackingMetrics

Pass the affiliate ID as a URL parameter, store it in a cookie, and configure the platform to capture that value as a custom field so every inbound call is attributed to the correct affiliate.

If you're building or managing your own affiliate program and expect significant call volume, Ringba or CallTrackingMetrics are often the strongest choices because they're designed to preserve affiliate attribution through to the phone call and support automated conversion reporting.

Yes. What you need is call tracking with dynamic number insertion (DNI) combined with affiliate click IDs (subID, aff_sub, click_id, etc.). The call tracking platform captures the affiliate ID from the landing URL, stores it in the visitor session, swaps in a unique phone number, and attributes any resulting call back to that affiliate.

A typical flow looks like this:

Affiliate Link
   ↓
https://yoursite.com/?aff_id=123&click_id=abc123
   ↓
Call tracking script stores aff_id + click_id
   ↓
Dynamic phone number displayed
   ↓
Customer calls
   ↓
Call attributed to affiliate 123
   ↓
Webhook/API sends conversion back to affiliate platform

Here are the strongest options:

Community recommendations consistently put CallRail, CallTrackingMetrics, and WhatConverts among the easiest solutions for tying calls back to marketing parameters like UTMs and click IDs. www.reddit.com

If you're running an affiliate program

The ideal setup is:

1. Affiliate platform generates:

   ?affiliate_id=45
   ?click_id=8fj39f

2. Call tracker stores those values.

3. When a phone call occurs:
   • duration
   • caller
   • recording
   • affiliate_id
   • click_id
   • campaign

4. The call tracker sends a webhook to your affiliate platform:

   {
     "affiliate_id":45,
     "click_id":"8fj39f",
     "conversion":"phone_call",
     "qualified":true,
     "value":250
   }

This lets you pay affiliates only for qualified calls or sales.

If you use affiliate software

Most modern affiliate platforms support this via APIs or postbacks:

• Everflow
• TUNE
• Impact
• PartnerStack
• Tapfiliate
• FirstPromoter

The call tracking system becomes the source of truth for the phone conversion and reports it back to the affiliate platform.

My recommendation

• Small to medium affiliate program: CallRail
• Serious affiliate network with custom rules and payouts: CallTrackingMetrics
• Need both form and phone attribution in one dashboard: WhatConverts

One important question

Are your affiliates sending traffic to:

• your own website (where you control the landing page and phone number), or
• a unique phone number directly (pay-per-call style)?

The best architecture is different depending on whether you're tracking web → phone or phone-only affiliate campaigns.
