How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.

Why calls need their own software
Phone calls still drive the highest-value conversions in insurance, home services, legal, finance and healthcare, but a call that arrives without attribution is a marketing black box. Pay per call software fixes that: it tracks which campaign, keyword or publisher produced each call, routes calls to the right buyer in real time, records and analyzes conversations, and proves ROI to clients or leadership.
The eight platforms below were all verified live in October 2026. They split roughly into two camps: purpose-built pay per call platforms for networks and performance marketers, and call tracking tools for agencies and brands. Both are included because buyers search for both under the same term.
#1
Ringba
Best for: Pay per call networks, publishers and performance marketers that need real-time routing at scale
Visit ringba.com
Starting priceSee website
Free planFree trial available
Ringba is the name that comes up first in pay per call circles, and its homepage makes the positioning clear: inbound call tracking and analytics for marketers, brands and pay per call, with no contracts or commitments. The platform offers on-demand telecom access in 60+ countries, intelligent call routing, real-time analytics and the Ring Tree marketplace where call buyers bid in real time.
For networks and publishers, the combination of routing flexibility, partner management and white-label options is the core appeal. The TCPA Shield compliance tooling addresses the regulatory reality of the space. If your business is calls, Ringba is the specialist's choice.
What we like- Purpose-built for pay per call
- No contracts, minimums or overages
- Ring Tree real-time bidding marketplace
- AI and automated compliance features
Watch out for- Pricing not published
- Power-user interface has a learning curve
- Overkill for simple call tracking needs
#2
CallRail
Best for: Agencies and SMBs that want call tracking plus AI lead engagement in one plan
Visit callrail.com
Starting priceFrom $55/month
Free planFree trial available
CallRail is the mainstream call tracking choice, and its vendor-published pricing makes it easy to evaluate: plans start at $55 per month. The platform connects campaigns, conversations and customers with call tracking, text, forms and attribution, now extended with Voice Assist AI that answers calls, qualifies leads and books appointments around the clock.
With 7,000+ marketing agencies on the platform, CallRail understands the agency workflow: multi-client management, white-label reporting and integrations with the ad platforms and CRMs agencies already use. For pay per call buyers rather than sellers, meaning businesses that receive calls from their marketing, it is the most accessible starting point.
What we like- Plans start at $55/month, published on the homepage
- 225,000+ businesses
- Voice Assist AI qualifies leads and books appointments
- 50+ integrations
Watch out for- Less specialized for pay per call networks than Ringba or Retreaver
- AI features cost more on higher tiers
- Per-minute overages add up at volume
#3
Invoca
Best for: Large B2C brands that want AI agents and conversation intelligence tied to revenue
Visit invoca.com
Starting priceSee website
Free planNo
Invoca has moved beyond call tracking into AI-powered revenue conversion. Its AI agent, Nico, engages inbound leads by voice and SMS around the clock, booking appointments and qualifying prospects before a human ever picks up. The platform connects every touchpoint in the buyer journey to revenue, which is why large B2C brands in telecom, healthcare, home services and insurance use it.
The vendor reports meaningful outcomes: higher contact center close rates, more marketing-driven leads and more appointments booked. This is enterprise software with enterprise economics, but for companies where phone calls drive the business, the ROI case is direct.
What we like- Nico AI agent engages and qualifies leads 24/7 via voice and SMS
- Strong outcomes with major B2C brands
- Connects online and offline touchpoints to revenue
Watch out for- Enterprise pricing and sales process
- No public pricing
- More than smaller businesses need
#4
WhatConverts
Best for: PPC and SEO agencies that need lead tracking across calls, forms and chats
Visit whatconverts.com
Starting priceSee website
Free plan14-day free trial
WhatConverts is the agency favorite for lead tracking: one report showing every call, form, chat and transaction attributed to the marketing that produced it. The homepage offers a 14-day free trial with easy setup, and customer reviews consistently praise both the product and the support.
For pay per call use cases on the buyer side, the strength is proving value to clients: show exactly which campaigns produced which calls and what those calls were worth. It lacks the publisher-side routing and bidding features of true pay per call platforms, but for agencies tracking calls for clients, it is one of the best-regarded options.
What we like- 14-day free trial with easy setup
- Tracks calls, forms, chats and transactions in one report
- Strong agency reputation
- G2 usability awards
Watch out for- Pricing amounts not shown on the homepage
- Less pay-per-call-network functionality than Ringba
- Smaller company than CallRail
#5
Retreaver
Best for: Publishers and networks that need advanced call routing with real-time buyer bidding
Visit retreaver.com
Starting priceSee website
Free planNo
Retreaver is a direct specialist competitor to Ringba in the pay per call infrastructure space. Its routing engine automatically sends calls to the highest-bidding buyers in real time, and its call rescue feature redirects the call to the next available buyer if one hangs up, saving revenue that would otherwise be lost.
The numbers are serious: 350 million calls routed since 2012, with a 4.9 out of 5 rating on G2. Support gets unusual praise in reviews, with a dedicated North American team. For publishers and networks comparing Ringba alternatives, Retreaver deserves a demo alongside it.
What we like- Smart routing to highest-bidding buyers in real time
- Call rescue redirects hang-ups to the next buyer
- 350M+ calls routed since 2012
- 4.9/5 on G2
Watch out for- No public pricing
- Pay-as-you-go minutes model needs cost modeling
- Smaller brand than Ringba
#6
Phonexa
Best for: Enterprises running pay per call and pay per lead at scale with compliance needs
Visit phonexa.com
Starting priceSee website
Free planNo
Phonexa is the enterprise operating system for performance marketing: call tracking, lead tracking, distribution, email and SMS marketing, accounting and fraud protection in one integrated suite. The pay per call side supports every major distribution flow, including ping trees, Ping Post and AI call agents, with granular attribution by publisher, source and location.
The compliance story matters in this space: proactive fraud protection, suppression list management and SOC 2 Type II certification suit regulated industries like insurance and finance. White-labeling lets networks run partner portals under their own brand. For large-scale operations, Phonexa replaces a stack of point tools.
What we like- Unified pay per call and pay per lead suite
- Ping tree and Ping Post call distribution
- Fraud protection and FCC/TCPA compliance
- SOC 2 Type II certified
- White-label partner portals
Watch out for- Enterprise pricing not published
- Platform breadth takes implementation effort
- Overkill for small operations
#7
CallTrackingMetrics
Best for: Sales and marketing teams that want conversation analytics across calls, texts, chats and forms
Visit calltrackingmetrics.com
Starting priceSee website
Free planSee website
CallTrackingMetrics positions itself as conversation analytics for sales and marketing, going beyond tracking into what happens on the call. The AI layer transcribes, analyzes sentiment and answers questions about conversations, while workflow automation routes leads and triggers follow-ups. A full business phone system with a customizable softphone means sales teams can work entirely inside the platform.
For pay per call buyers, the appeal is closing the loop: attribute the call, analyze the conversation, coach the team and sync everything to the CRM. Agencies get flexible sub-accounts with white-label and custom billing options. It is a strong pick when calls are the start of a sales process, not the end of one.
What we like- AskAI conversation intelligence
- Full business phone system with softphone
- Strong agency sub-account and white-label structure
- SOC 2 with HIPAA, GDPR and CCPA support
Watch out for- Pricing not published on the homepage
- Breadth can overwhelm simple tracking needs
- Enterprise features add cost
#8
Nimbata
Best for: Agencies and marketing teams that want call attribution and AI insights at a fair price
Visit nimbata.com
Starting priceFrom $39/month
Free planFree trial available
Nimbata is the value pick that does not feel like a compromise. The vendor lists pricing from $39 to $149, and the platform connects every inbound call to the campaign, keyword and page behind it, then uses AI to capture intent, outcomes and lead quality automatically. Setup takes under ten minutes with no credit card required.
With 7,000+ agencies and marketing teams on board and a 4.7 rating on G2, Nimbata has earned its place. For agencies that need to prove ROI on call-driven campaigns without enterprise budgets, it is one of the easiest recommendations on this list.
What we like- Vendor-listed pricing from $39 to $149
- AI-powered call notes and lead qualification
- 7,000+ agencies and teams
- No credit card required to start
- 4.7 on G2
Watch out for- Smaller company than CallRail or Invoca
- Fewer enterprise features
- Pay per call network features are lighter than Ringba

How we chose these eight
We split the category deliberately: purpose-built pay per call platforms (Ringba, Retreaver, Phonexa) for networks, publishers and high-volume buyers, plus leading call tracking tools (CallRail, Invoca, WhatConverts, CallTrackingMetrics, Nimbata) for agencies and brands. Every vendor homepage was opened and verified in October 2026. One merger note: DialogTech was acquired by Invoca, so we list only Invoca rather than both.
We weighted call routing and distribution capabilities, attribution depth, AI and conversation intelligence, compliance features, agency-friendliness and honest pricing. The final list covers the full range from free-trial-friendly tools to enterprise suites.
What to check before you buy
First, decide which side of the call business you are on. If you sell or distribute calls to buyers, you need routing, bidding and publisher management: Ringba, Retreaver or Phonexa. If you receive calls from your own marketing, you need attribution and conversation intelligence: CallRail, Nimbata, WhatConverts, CallTrackingMetrics or Invoca.
Next, model the real cost. Per-minute charges, number rentals and AI feature fees add up fast at volume. Run your actual call numbers through each vendor's pricing before signing, and ask about overages, minimums and what happens in your peak month.
Finally, test attribution with your actual campaigns. Set up tracking numbers on a live campaign during the trial and verify that calls attribute correctly to keywords and ads. The platforms that make this easy in a trial will be easy to live with long term.
