V20 - Barge-in/ Listen/ Whisper not working

[Remco Straaten]

Dear forum members,


I have a customer who has been using 3CX for a long time. Recently, they’ve encountered an issue: they are no longer able to listen in, barge in, or whisper to their colleagues. The error message they receive is:


"Destination is not reachable."


The user has the Manager role, and the appropriate permissions are checked under the Department settings.


Does anyone know how we can resolve this issue?


Thank you in advance!

Have you checked it is ticked under the "view" tab of extension too?

Are they in same departments?

Hi,

Yes they are in the same department.

Does this happen for anyone who has access to barge in/listen or just this extension (manager)?
Also does this happen with any extension they are trying to barge in/listen or only if they try to barge in/listen into a specific extension?

Hi Andreas,

Every user has the same problem. They all got manager role.

Hi @Remco Straaten

I sent you a PM

For anyone else who might see this in the future, the issue was caused by an IP phone rejecting the Barge-in call.

Having the same issue with Yealink T43U/46U phones. Listen/Barge works with the Windows App only and is not ringing
the hardware IP phones or the mobile app anymore.
