Problems no sound in between internal extensions after upgrade

[bferreira]

Hi,

I only use extensions on my computer and cell phone. I don't have physical phones.
Details:
3CX Version Standard Annual 16.0.5.454
Server OS - Windows Server 2019 (My Server)
Has the Firewall Checker passed: YES

I am having problems after upgrading to this version (16.0.5.454 ).
Users call for internal extensions and when answering there is no audio.

I have the automatic updates turned off, but still the system did without any action the upgrade. I did roolback and everything started working but hours later the system ran the update again and the problem returns.

I verified that if the client that makes the call has version 16.3.0.144 and the recipient has version 16.0.1.8 it works, otherwise it does not. And if both customers are at version 16.3.0.144 it doesn't work either.

Can you help me?
If you need any more information, please ask.

Thanks.

Are outside calls also affected? Have you looked at the 3CX Activity Log for any error massages? Might it be a Codec incompatibility issue?

First of all, thank you so much for your help. I'm trying to implement this solution and for me this is all new.

Calling the 3cx app windows out (external numbers) works without problems.

I verify now:

[CM503003]: Call(C:32): Call to <sip:[email protected]:0> has failed; Cause: 487 Request Terminated/INVITE from 127.0.0.1:5483

MediaProxy:VRTP receiver for [email protected]:5482(C:32.3) has no assigned socket

Does this help?

Thanks

Found the same log, (MediaProxy:VRTP receiver for [email protected]:5482(C:32.3) has no assigned socket ) in the second log posting, in this thread...

It's the first time I can recall coming across that particular log. Someone else may be more familiar with it.

Hi @bferreira

I'm wondering why you are on version 16.0.5.454 which is the Alpha 2 Build from February 2020

You should be on the final stable release of the PBX which is version 16.0.5.611
