Solved No audio when transferring calls on Yealink handsets in remote office

[rogerlightfoot]

We have an Enterprise Licence Version 16.0.9 running on Windows Server 2019.

Our handsets are Yealink T46S running 66.86.0.5.

In our main office transferring calls is fine. In a remote office where the handsets are provisioned via STUN everything is fine except for transferring calls to other handsets.

When we try to transfer a call neither party can hear the audio.

Please could somebody point me in the right direction as far as troubleshooting and solving this is concerned.

Many thanks

Roger

STUN is bad mmmkay. You should be using a SBC.

Additionally, ensure PBX delivers audio is turned on for the extensions.

But really, just use a SBC.

Thank you SO much - that has fixed it.
