The problem
You're losing customers before they cancel.
You don't lose subscribers the moment they call to cancel. You lose them weeks earlier, when they feel unheard, hit an unresolved issue, or start wondering if another provider might serve them better. Most churn signals show up well before a cancellation request, often in subtle call cues or service problems. By the time your team hears about it, it's already too late.
What if you could see it coming?
Catch the signal, then step in early.
With Sonar Retain you can. The system analyzes 100% of your customer calls to detect churn signals before they turn into disconnects.

Connects to your VoIP provider to capture and analyze every support call recording, not a sample.
Churn prediction
Detects churn signals in call cues and service issues weeks before a cancellation request lands.
Quality observability

Powered by QueSee.
Sonar Retain integrates directly with your VoIP provider to capture 100% of support call recordings, with no workflow disruptions and no manual effort.
