If your business relies on inbound calls and cross-channel marketing campaigns, attribution might be one of your top priorities, and for several reasons. Not only does proper call tracking software with attribution ensure your partners are properly credited – which sparks motivation and boosts performance – but it also surfaces actionable business data, suggesting which strategies to leave out and which to double down on.
“As long as you’re tracking your calls in the same way that you track your web leads in terms of attributing value back to all of your media buying platforms, whether it be your social media platforms or Google or wherever you’re doing, let the algorithm do its thing and go away.
Allowing the algorithm to target customers is valuable for you. A lot of people will track every little last thing out of their web leads to make sure they’re optimizing their advertising spend, but they don’t do it for calls. So I think calls are getting treated maybe unfairly, not being tracked to the same level. You’re just not letting the platforms do their thing.” – David Pickard, CEO, Phonexa, during the Pioneering Pay-Per-Call Excellence webinar
To attribute calls efficiently, you need software that incorporates either static tracking numbers or dynamic number insertion (DNI), a technology that assigns a unique number to each web session, enabling you to extract the maximum data from every interaction.
Once such a number is dialed, a call tracking solution unifies caller attributes in real time, enabling smart, almost instantaneous routing and professional follow-ups that meet prospects where they are – something 71% of consumers expect.
Using our brand evaluation methodology, a bedrock of all Phonexa’s listicles, we conducted research and reviewed the 11 best call tracking software products. Read on to discover their features and determine which solution is the right one for your business.
How We Evaluate & Compare Platforms
To maintain objectivity, Phonexa’s specialists follow a specific brand research and assessment methodology that ensures you receive a clear, unbiased view of the market:
- Pull 24 months of website performance data from SimilarWeb, including traffic sources and patterns, and all sorts of on-page behavioral data – such as bounce rates, time on page, and pages visited.
- Manually review each platform’s toolkit and build a feature-by-feature comparison table for the category.
- Check user reviews across G2, Capterra, TrustRadius, Product Hunt, and Trustpilot, accounting for overlap where sites share the same review pool (e.g. G2/Capterra/GetApp/Software Advice), then run a manual pass on product-promise alignment, pricing and feature transparency, and real-world usability.

Ruler Analytics: Full-Funnel Attribution That Treats Calls as One Signal Among Many

Ruler Analytics is a marketing attribution software that offers call tracking alongside form tracking, live chat tracking, and offline conversion import.
Best For
Marketing teams that want calls measured as part of a wider attribution model. The platform’s attribution methods and marketing mix modelling can also measure channels that don’t generate clicks, such as TV, radio, or out-of-home ads.
Key Capabilities of Ruler Analytics
- Calls as one input to unified measurement: Dynamic number insertion puts tracked calls in the same customer journey as forms, chat, and CRM revenue, rather than in a separate report.
- Attribution beyond last click: Multi-touch, data-driven, and impression models let you credit channels that influence a sale without generating the final click.
- Marketing mix modelling for the untrackable: Budget scenario planning and diminishing-returns forecasting for top-of-funnel spend that attribution alone can’t capture.
- Thin on call-specific features: No transcription and no call routing. It records and attributes calls, but doesn’t analyse conversations.
