What tools are call centers using for call tracking and analytics?

I’m trying to understand how call centers manage and analyze large volumes of inbound calls.

A lot of teams still rely on simple call logs, but that doesn’t really show which campaigns or channels are driving the calls.

Recently I came across tools like CallAtlas that claim to track call sources, record conversations, and provide analytics for performance insights.

For those running call centers or pay-per-call campaigns, what tools are you using to track and optimize calls?

Would be great to hear what’s working for you.
