What CallRail does
CallRail answers a marketing question: which campaign produced this phone call? You give each ad, listing or traffic source its own tracking number, and a JavaScript snippet on your website swaps the number a visitor sees based on where they came from (dynamic number insertion). Calls forward to your existing phones, and CallRail records each one and reports it against the source, campaign and keyword. Texts and, on Complete plans, web forms are tracked the same way. Data flows to Google Ads, Google Analytics, Microsoft Ads, Meta, HubSpot, Salesforce and 50+ other tools, so a call can count as a conversion. CallRail says 220,000+ businesses and 7,000+ agencies use it.
CallRail sits alongside a phone system rather than replacing one. Call flows route calls to the right person, and a unified inbox lets staff answer and return calls and texts on tracking numbers, but most businesses keep their main phone service. On the AI side, every plan gets call transcription; Lead Conversion plans add Premium Conversation Intelligence (call summaries, sentiment, keyword spotting, trend reports and automatic conversion tagging). Voice Assist is a separate AI agent that answers calls around the clock, qualifies leads and books appointments.
