How does call tracking software work?

Tracking phone calls is vital for analyzing which marketing activities are making customers pick up the phone.

Phone call tracking works by enabling you to assign unique tracking numbers to your marketing campaigns. When a customer picks up the phone, you’ll be able to see which activity led to the call.


Having this information makes it easier for you to sell morestreamline operational processes, and optimize marketing budgets.

That’s why Infinity’s cloud-based call tracking solution is an important tool in the tech stack for marketing, sales, customer service, and contact centers.
