Overview

Call Tracking assigns dedicated phone numbers to marketing campaigns, channels, or individual web visitors. When someone calls, Callr captures the source attribution alongside the full call data — which campaign, keyword, or ad creative drove the call.

How it works

Provision a pool of numbers via the API or Portal. Assign numbers to campaigns (static tracking) or swap them dynamically per web session (dynamic number insertion). Each call is tagged with its source. In the hangup branch, push attribution data alongside CDR, recordings, and AI analysis to your analytics platform via fetch@v2.

Use cases

Performance marketing: measure which campaigns drive phone leads. Real estate: track calls from individual property listings. Automotive: attribute dealership calls to specific ad placements. Marketplace platforms: measure seller and buyer call engagement by traffic source.
