Solved 3CX - Yealink T41s - Jabra 920 Echo

[Mike Hammett]

Just moved a customer to 3CX and Yealink from FreePBX and Polycom. They have Jabra 920 headsets. We got the adapters for Jabra headsets to Yealink phones. They are experiencing a prominent echo on the remote side when using the headset. I upgraded the phone's firmware and template. I upgraded the headset's firmware.

The echo remains.

The remote caller hears themselves echoing. The remote caller does not hear an echo in the local caller. The local caller hears no echo.

This only happens on the headset. The handset and speaker don't have the problem.

Thoughts?

Hi Mike,

Take a look on the headset manufacturer FAQ website, they have some suggestions for controlling this

I did find it to be a headset issue and not a 3CX issue. There's a dial on the back of the headset base that needed to be set to A. The manual was largely useless, saying to turn the dial to get a clean dial tone, implying channel changes when it had nothing to do with that.
