Infinity vs CallRail: Which is the best fit for your marketing team?

The short version

Choose Infinity

Infinity is likely the stronger fit if you want to:

Connect marketing activity and customer journeys to calls, outcomes and revenue across more than the US, Canada, UK and Australia – Infinity supports call tracking in 75+ countries
Get a conversation-intelligence suite with ready-built applications – Smart Outcomes, Conversion Barriers, Smart Voice – each mapped to a specific commercial question, not a generic call score
Operate as a mid-market or enterprise marketing team, with a Customer Success structure, formal security certification (ISO 27001, PCI DSS Level 1) and G2-verified support scores built around that complexity
Get expert help – an Insights & Intelligence team, Rapid Insights Projects, Professional Services – built into the relationship, not a self-serve knowledge base
Optimise paid media across Google Ads, Search Ads 360, Microsoft Advertising, Meta, LinkedIn and Campaign Manager 360, not a predominantly Google-Ads-centric setup.

Consider CallRail

CallRail may fit better in a number of cases:

Your operation is entirely within the US, Canada, UK or Australia and broader international coverage isn’t a requirement
You want a broader small-business toolkit alongside call tracking – form tracking, live chat, lead capture and outbound dialling in the same platform
You value a large, mature, self-serve product.

CallRail is not a small or unsophisticated platform – it has shipped an AI voice agent and an AI-driven bidding signal within the last couple of years, and we won’t understate that. But its scale comes from serving a very large volume of smaller, single-market businesses. If you’re a marketing team managing more complexity, more markets or more brands, the question is whether the platform built for that volume is also the platform built for your depth.

Proof up front

Fred. Olsen Cruise Lines used Smart Outcomes to identify calls showing genuine booking intent and fed those signals back into Google Ads. The result:

16% Increase in return on Google Ads spend

37% Year-on-year increase in revenue

The support we’ve received has been invaluable. We couldn’t have run the project without them. They’re extremely knowledgeable, easy to work with, and always there to offer guidance and answer questions.

Digital Performance Manager, Specsavers

Why Infinity is different

The honest answer to “which platform has more features?” is: it depends which features you count. That’s exactly why we don’t sell a feature catalogue. We start with the commercial outcome you’re trying to improve, then assemble the combination of call tracking, AI, CRM data and activation that gets you there – because a first-party call outcome signal is only worth having if performance marketers can act on it, not just report it.

Built around your growth model,
not a plan tier

The right mix of Call Tracking, AI, CRM data, revenue matching and activation depends on your customer purchase journey, the length and complexity of your sales cycle, the volume and quality of your conversions, your average order value, and the platforms controlling your marketing investment. We scope around those – so you get a solution built to create measurable value, not a larger bundle of features to configure and manage as you grow.

The right signal for your bidding strategy

A high volume of immediate phone sales? Feeding revenue into value⁠-⁠based bidding is probably your lever. A longer sales cycle? An earlier signal – strong buying intent, an appointment request, a qualified opportunity – will move performance faster. We help you choose between call signals, context signals, intent signals, outcome signals and revenue signals based on how your customers actually buy, so your bidding platforms receive something more useful than “a call happened.”

AI applications, not a call score

Conversation Analytics identifies why customers call, what happened in the conversation, and whether it produced a valuable outcome – with searchable transcripts and summaries so you can analyse conversations at scale. Smart Outcomes and Conversion Barriers turn that analysis into specific, ready-built applications rather than a generic score.

Smart Voice extends the same loop to missed and out-of-hours calls – answering the caller, understanding why they’re getting in touch, capturing lead details and supporting booking workflows, then feeding that conversation back into Infinity as structured data.

Enterprise capability
with a hands⁠-⁠on partner

We support high-volume, multi-location and multi-market organisations without losing sight of what an individual customer is trying to achieve: a Success Plan aligned to your objectives, dedicated Customer Success, 24/7 support, regular Business Reviews, access to Solutions and Professional Services, and executive sponsorship for strategic accounts. Underneath it all sits the security posture enterprise teams need as standard – ISO 27001 certified, PCI DSS Level 1, GDPR data controls with automatic redaction of sensitive call details, multi-zone cloud availability – detailed on our security and stability page. The goal isn’t to deploy technology. It’s to keep improving how your conversations create value.

One loop from campaign to revenue

Infinity connects the campaign, keyword and customer journey to the resulting phone conversation, the customer’s intent and outcome, the downstream CRM or sales result, the revenue created, and the signal returned to the platforms controlling your future spend.

So instead of a report on which campaigns generated calls, you see which activity generated the right calls, the right outcomes and the revenue to prove it.

Integrations judged by the workflow, not the logo count

We provide a complete set of out-of-the-box integrations across advertising, analytics, CRM, reporting and marketing technology, backed by APIs, webhooks and Professional Services. An integration logo doesn’t guarantee your specific workflow works – so we start with what data needs to move, where it needs to appear, when, what action it should trigger, and how you’ll measure success.

The Infinity Loop Fit Check
A fairer way to compare than a feature list

With a platform as broad as CallRail, a feature table will always look busy. It still won’t answer the question you came here with: which platform will move your marketing performance, and what will it take from your team to get there?

The Infinity loop

Every Infinity solution is built around the same loop – designed to complement the stages of your established optimisation processes:

1. Capture the customer journey and conversation

2. Signal what it means – intent, outcome, value

3. Prioritise the calls and campaigns that matter most

4. Activate that signal in the platforms controlling your spend

What is the Infinity loop?

Marketing is a continuous cycle of measuring, learning, and improving.

But most optimisation decisions are made using incomplete signals, because customer conversations never make it into the process.

Infinity closes that gap by transforming first-party conversation data into AI⁠-⁠driven signals that reveal what's happening, what's blocking conversion, and where to act next.

Every signal makes your loop smarter – helping you improve performance, reduce waste, and grow revenue faster.

Loop stage	The question to ask	CallRail	Infinity
Capture	Does it connect the full journey behind every call – not just the fact one happened?	Dynamic number insertion and multi-channel attribution across calls, forms, chat and text.	Visitor-level tracking connects campaign, keyword and journey to the call – and to what happened afterwards – across 75+ countries, so international brands can run one model everywhere they operate.
Signal	Does it turn the conversation into intent, outcome and value signals – and does it come packaged for a specific job, or as a general score?	Conversation Intelligence transcribes, tags and scores calls, and its newer Conversion Signals feature pushes weighted call values into Google Ads – sold as an upgrade over base Call Tracking.	Conversation Analytics ships with Smart Outcomes and Conversion Barriers as ready-built applications, each aimed at a specific commercial question rather than a generic score, and activated across a wider set of ad platforms than Google Ads alone.
Prioritise	Does it show which calls, campaigns and customers are actually worth acting on?	Call scoring and lead qualification highlight which calls look valuable; we found no packaged tool specifically built to diagnose why a good call didn’t convert.	Conversion Barriers is built specifically to find and act on the friction stopping high-intent calls from converting – a marketer’s question, not just a lead score.
Activate	Does the signal reach the platforms controlling your spend, without heavy build?	Strong Google Ads integration and 60+ tool connections via Voice Assist; activation is predominantly built around Google’s ecosystem.	An entire range of integrations built specifically for marketing activation – Google Ads, SA360, Microsoft Advertising, Meta, LinkedIn, Campaign Manager 360 – plus APIs and Professional Services for the rest.

What independent
reviewers say

On the current G2 comparison, CallRail holds a 4.5-star rating from 1,829 reviews; Infinity holds 4.6 stars from 157 reviews. Both are strong scores, and the sample sizes are genuinely different, so treat the comparison as directional rather than a like-for-like sample. CallRail rates higher on ease of use, ease of setup and ease of administration – a fair reflection of a mature, high-volume, self-serve product. Infinity rates higher on quality of support, being a good partner in doing business, and product direction.

Reviewer profiles show the clearest difference: 74.5% of CallRail’s reviewers are small-business users, against 43.8% mid-market and 27.1% enterprise for Infinity – only 3.2% of CallRail’s reviews come from enterprise users.

G2 lists Conversation Intelligence Software as a category both platforms now qualify for, evenly matched at 8.4 (CallRail, 244 reviews) and 8.5 (Infinity, 22 reviews); Speech Analytics Software is listed as a category unique to Infinity.

G2’s own top-cons data for CallRail cites Missing Features (33 reviews) and Integration Issues (30 reviews) as the most common complaints.

Beyond the software
Professional Services and Rapid Insights Projects

A self-serve platform hands you the data and wishes you luck. That’s fine when the questions are simple. When they’re not – when leads aren’t converting and nobody knows why, when spend is leaking somewhere in a journey – you want an analyst, not a knowledge base.

Rapid Insights Project

That’s what a Rapid Insights Project is: a fixed-price, fixed-scope answer to a specific question, typically in a matter of weeks. Our Insights & Intelligence team digs into your call transcripts, keyword data and marketing activity, and comes back with a clear, prioritised action plan rather than another dashboard.

Explore Rapid Insights Projects

Professional Services

Where the need is ongoing, Professional Services gives you continuous access to that same expertise – regular reviews, prioritisation and guidance so insight keeps turning into action as your goals change. Support scales from periodic reviews up to deep, ongoing technical partnership, depending on how much help you need.

Explore Professional Services

Partnership programme

Agencies get the same treatment, not an afterthought: a dedicated agency partner team plus a certification programme built to help agency teams extract full value from their clients’ call analytics data – capability that has contributed to paid media award wins for Infinity agency partners.

Explore partnership certification

CallRail’s support model is built to serve a very large volume of customers efficiently – a different job to a scoped, ongoing analytical partnership, and we haven’t seen a dedicated insights or conversation-intelligence consultancy function publicised as part of its offering. If expert analysis matters to your evaluation, ask each vendor directly what’s included.

Call tracking and marketing attribution

CallRail’s foundation covers a lot of ground: dynamic number insertion and multi-channel attribution across calls, forms, live chat and text messaging, in the US, Canada, UK and Australia. For a business operating solely in those markets, it’s a mature starting point. Infinity’s Call Tracking adds visitor-level tracking that connects the channel, campaign and keyword behind every call to the pages visited before and after the conversation, across 75+ countries – the difference that matters most for international or multi-market brands, who otherwise end up running different measurement models in different territories.

Conversation
intelligence and AI

CallRail has invested here, and the facts deserve stating accurately. Premium Conversation Intelligence transcribes calls, spots keywords, tags conversations and analyses sentiment; Conversion Signals, launched in 2025, pushes weighted call values into Google Ads so Smart Bidding can optimise towards higher-value calls.

Now the two questions those facts don’t answer. First, packaging: CallRail sells conversation intelligence as an upgrade over its base Call Tracking plan, built primarily around Google Ads activation. Second, breadth: for a smaller business optimising one channel, a Google-centric signal is a reasonable place to be – but an enterprise marketing team runs a media mix, and a signal that only reaches one platform optimises one slice of it.

Infinity ships Conversation Analytics with ready-built applications already sitting on top of it, each aimed at a specific job:

Smart Outcomes

Identifies intent and outcome on every call out of the box, and is designed specifically to feed paid-media bidding across Google Ads, SA360, Microsoft Advertising, Meta, LinkedIn and Campaign Manager 360 – see Paid Media Optimisation below.

Conversion Barriers

Takes the same underlying analysis and applies it to a different question: not what happened, but why a good call didn’t convert – see Conversion Improvement below.

Smart Voice

Extends the loop to calls that never got answered at all – see Revenue Recovery below.

CallRail’s Voice Assist answers calls, reads caller intent, qualifies leads and books appointments via Calendly or Google Calendar. Infinity’s Smart Voice does the equivalent job – answering, understanding intent, capturing lead details and supporting bookings – then feeds that conversation back into Infinity as structured data that flows through the same Conversation Analytics and Smart Match layer as every other call.

The question worth asking isn’t whether an AI voice agent exists on each side; it’s whether the signal it captures connects to the rest of your marketing measurement, or sits as a separate tool alongside it.

Applied to your use case

A signal is only as good as the result it changes.

Here’s how the Conversation Analytics suite and its applications map onto the three outcomes marketing teams usually come to this page to solve.

Paid media optimisation

Call Tracking connects every call to the campaign, advert and keyword that generated it. Smart Outcomes and Smart Match then turn that call into an intent, outcome and revenue signal fed straight into Google Ads, Search Ads 360, Microsoft Advertising, Meta, LinkedIn and Campaign Manager 360 – so bidding optimises towards value, not call volume, across your whole media mix rather than one platform.

Fred. Olsen Cruise Lines used Smart Outcomes to identify calls showing genuine booking intent and fed those signals back into Google Ads: a 16% increase in return on Google Ads spend and a 37% year-on-year increase in revenue.

Explore Paid Media Optimisation

Conversion improvement

Conversation Analytics and Conversion Barriers analyse conversations at scale to find the recurring objections, information gaps and journey friction stopping high-intent prospects from converting – then connect those patterns back to the campaigns and journeys that created them, so you know what to fix first.

Pendragon used this approach to achieve a 64% reduction in cost per acquisition and a 66% reduction in purchase-journey friction; Blue Bay Travel saw a 62.5% uplift in conversions.

Explore Conversion Improvement

Revenue recovery

Missed and out-of-hours calls are demand you’ve already paid to create. Smart Voice answers when your team can’t, understands why the caller is getting in touch and captures the enquiry, while Smart Match and CRM integrations attribute the recovered value back to its original campaign.

Ontrack achieved 93% fewer missed calls alongside a 45% boost in sales leads; Ramsay Health Care achieved 74% fewer missed calls.

Explore Revenue Recovery

CRM and revenue attribution

Smart Match connects confirmed sales and revenue to the call and marketing activity that generated them – helping you measure true ROI, identify the campaigns producing higher-value customers, support value-based bidding, and shift budget away from activity that creates volume without revenue.

Infinity’s Caller Insight integration brings marketing source, keyword, visitor activity and call information into Salesforce; Leads can be created directly from calls, and downstream outcomes flow back to Infinity, matched to the originating conversation and marketing journey. We also offer a native HubSpot integration and support other CRM workflows through APIs, webhooks and tailored services.

CallRail has a strong, well-documented presence in the HubSpot marketplace – HubSpot’s own case study material describes it as one of the most widely adopted calling integrations on the platform – alongside Salesforce and Google Ads integrations, and its Voice Assist product connects to 60+ tools directly.

Beyond call tracking:
CallRail’s broader small⁠-⁠business toolkit

Worth being clear-eyed about where CallRail has expanded. Independent G2 category data shows CallRail qualifying for form building, live chat, lead capture, outbound call tracking, marketing analytics, attribution and an AI sales-assistant category that Infinity doesn’t compete in – a broad, small-business-friendly lead-management toolkit built around its call-tracking core.

Infinity has deliberately not built in that direction, and the reason is the customer we serve.

Our focus stays on the call and conversation as a marketing-performance signal – attribution, conversion and revenue – for teams whose primary need is proving what marketing spend produced and improving it, not running forms, live chat and outbound dialling from the same platform. If a single, broader small-business toolkit is what you’re after, that’s a fair reason CallRail may be the better fit. If extracting more growth from the conversations you’re already paying for is the job, breadth of toolkit isn’t the thing that will get you there.

Integrations and technology fit

Infinity provides a full set of out-of-the-box integrations, supported by REST APIs, real-time caller-context APIs, call-event webhooks, CRM outcome feeds, and call, visit, goal and transaction exports, plus Professional Services for anything more tailored. CallRail offers a broad integration marketplace of its own, with particularly strong reach into HubSpot, Salesforce and Google Ads, and Voice Assist alone connects to 60+ tools.

Logo-counting is the wrong test on both sides. Better questions: does the specific integration you need exist, does it support your exact workflow, what data moves in each direction, does it need extra development, who maintains it, and what commercial decision will it actually improve?

Implementation
and time to value

Installing a tracking script is the easy part. What shapes your result is everything scoped around it: your business objectives, key journeys and conversion points, telephony and number requirements, CRM and advertising workflows, reporting needs, and the signals most useful to your bidding platforms – all of which feed your Success Plan and rollout.

Typical time to value: Call Tracking live within a week; outcome signals improving optimisation from around day 30; revenue signals driving measurable ROAS and CAC improvement within 90 days.

Value, not just price

CallRail’s plans scale with usage and feature tier, and conversation intelligence and Voice Assist sit above the base Call Tracking plan as upgrades – a sensible model if you want to grow into AI features gradually, and a fair one for the businesses it’s built for.

The more useful comparison isn’t the headline monthly fee on either side. It’s what’s included at each stage, what you’d need to add as your call volumes and ambitions grow, and how much of that growth is handled through self-serve upgrades versus a scoped relationship with dedicated support. We’ll work with you to scope a solution around the outcomes you need, rather than equate value with the number of features switched on.

Which platform is the better fit?

We think Infinity is the stronger choice when you’re operating across more than one country or market, when conversation intelligence and an AI voice agent need to connect into one attribution and revenue-reporting model rather than sit as separate tools, when paid-media activation needs to reach beyond Google Ads, when formal security certification matters to your industry, and when dedicated Customer Success, an Insights & Intelligence team and Professional Services matter more than self-serve scale.

CallRail is a reasonable, often strong choice in a genuine set of cases: your operation sits entirely within the US, Canada, UK or Australia, you want form tracking, live chat, lead capture and outbound dialling alongside call tracking in one product, or you value a large, mature, self-serve platform.

Frequently Asked Questions

Is Infinity a good alternative to CallRail?

Yes, particularly for marketing teams operating across more than one country or market, or that want conversation intelligence and paid-media signal working automatically across every call rather than as a configured Q&A layer. CTM remains a strong option for US-based businesses that want a broad communications and contact-centre platform alongside call tracking.

What’s the main difference between Infinity and CallRail?

CallRail is a large-scale platform built around call tracking, lead capture and a broad small-business toolkit, predominantly for the US, Canada, UK and Australia. Infinity is built specifically around first-party call outcome signals for marketing teams, with coverage across 75+ countries – including the US, Canada, UK, European territories and Australia – and enterprise-grade Customer Success and security as standard.

Does CallRail offer AI conversation intelligence?

Yes. Premium Conversation Intelligence transcribes, tags and analyses calls, and its Conversion Signals feature pushes weighted call values into Google Ads for Smart Bidding. Infinity ships Conversation Analytics with Smart Outcomes and Conversion Barriers as ready-built applications, activated across a broader set of ad platforms than Google Ads alone.

Does CallRail have an AI voice agent?

Yes. Voice Assist, launched in 2025, answers calls, reads caller intent, qualifies leads and books appointments 24/7. Infinity’s Smart Voice performs the equivalent role and feeds the resulting conversation back into the same Conversation Analytics and Smart Match layer as every other call, rather than as a standalone tool.

Does Infinity support international call tracking?

Yes – Infinity provides call tracking numbers and coverage across 75+ countries. CallRail’s coverage is currently limited to four territories.

Which platform is easier to use?

G2 reviewers currently rate CallRail higher for ease of use, ease of setup and ease of administration, reflecting its build as a self-serve product. Infinity rates higher on quality of support, being a good partner in doing business, and product direction.

How does Infinity handle security and compliance?

Infinity is ISO 27001 certified and PCI DSS Level 1, with GDPR data controls, automatic redaction of sensitive details such as payment card information, roles-based access, two-factor authentication and SSO – published in full on our security and stability page. For regulated industries and enterprise procurement, that certification is usually a requirement rather than a preference.

Does Infinity integrate with HubSpot and Salesforce?

Yes. Infinity offers a native HubSpot integration and a Salesforce integration (Caller Insight) that brings marketing and call information into Salesforce and can create Leads directly from calls. CallRail also has strong integrations with both platforms, including a leading position among HubSpot’s calling app integrations.

Can Infinity send call outcomes to Google Ads?

Yes. Infinity can send call, goal, intent, outcome and revenue signals into Google Ads, Search Ads 360, Microsoft Advertising, Meta, LinkedIn and Campaign Manager 360, depending on your setup. CallRail’s Conversion Signals feature does the equivalent job for Google Ads specifically.

Is Infinity cheaper than CallRail?

Pricing depends on platform scope, call volumes, functionality, services and your specific requirements. The more useful comparison is total cost and time to value – implementation, integration, internal resource and ongoing optimisation – not the headline subscription alone.

Request pricing

Can I migrate from CallRail to Infinity?

Yes. You’ll update your tracking numbers, replace the tracking script on your site, and recreate the integrations, reporting and historical comparisons you rely on – and Infinity’s Customer Success team plans that migration with you to protect continuity through the switch.

Does Infinity offer anything beyond the platform itself?

Yes – expert analysis, packaged two ways. Rapid Insights Projects answer a specific question (why leads aren’t converting, where spend is being wasted) at a fixed price and scope, typically within weeks. Professional Services provides the same expertise on an ongoing basis, keeping insight prioritised and actioned as your goals change. Agencies also get a dedicated partner team and certification programme.
