Infinity.co is an enterprise call tracking and analytics platform that teams shortlist when they need deep attribution and conversation analysis rather than a cheap tracker for their business.
This review covers what it does, what per-call pricing costs, and how Infinity compares with 9 alternatives, whether you want something lighter or a full phone system.
CallRail is an inbound call tracking software platform for small businesses and agencies, helping them understand which campaigns are bringing quality calls and which underperform and therefore need to be optimized or eliminated.
Plans run monthly from $50, with a 14-day trial and no demo required. CallRail is best for small businesses looking for a cheap call tracking on-ramp.
WhatConverts captures calls, forms, and chats as leads and pins sales value to them to identify revenue by source. This turns simple recordings into a report the marketing team can use to improve lead attribution and better understand leads.
You can get a paid account from $30 to $160 a month, and agency plans covering unlimited clients go from $500 to $1,250, with a 2-week trial. The catch is that WhatConverts values leads but never works them, so you still need a lead distribution layer on top.

Infinity.co is a call tracking and analytics software platform with two main features: call tracking that shows which campaign, keyword, or ad produced a call, and conversation analytics that reads the over-the-phone conversation once it starts.
Infinity.co reviews are positive, with a 4.6 rating based on 158 reviews on G2. Users comment on helpful and intuitive call tracking that integrates easily into their operations, but also flag that the platform has a high learning curve and provides inaccurate reporting on some occasions.
Infinity’s call tracking uses dynamic number insertion (DNI), which shows every visitor a unique call tracking number, connecting calls back to the exact source, campaign, and keyword. And when the call starts, Infinity’s speech analytics records and reads the calls, creating a summary with the caller’s intent and outcome, including sentiment analysis and a transcript.
Smart Match connects calls to revenue: You upload a sales report as a CSV, and the platform ties each sale to the call and the campaign that produced it. As for reporting, a real-time dashboard with custom goals and channel-level breakdowns allows you to see which sources drive quality calls.
The platform connects natively to:
Infinity holds ISO 27001 certification and PCI DSS Level 1. The platform’s conversation analytics detect and redact card numbers and personal data automatically, and its PII controls are built to keep call data within the GDPR guidelines.
The pricing plans include a flat monthly fee plus a charge per call, across 3 tiers on rolling monthly terms.
There isn’t a free plan or trial, but you can request a demo to understand the platform.

Call tracking assigns a unique phone number to each traffic source. When a lead calls, the software then identifies ads, campaigns, and keywords that sent them.
Infinity is best for enterprise teams that run on inbound phone calls, especially in phone-heavy sectors like healthcare, and that require analytics on conversations.
It depends on what you need beyond Infinity’s analytics. For a cheaper, self-serve tracker, CallRail. For an enterprise head-to-head on conversation intelligence, Invoca. For a team that wants to route and sell its calls and leads, Phonexa.
No, there’s no Infinity.co free trial. Instead, accounts have a demo they can use to understand the platform.
