Direct Routing to Teams Voicemail not working
Hi Guys,
We have recently discovered that PSTN callers to our Teams clients are unable to hear our Teams VM greeting nor leave VM messages. The VM works fine for Teams - Teams calls and we get the messages in our inbox just fine with that type of call but any PSTN call to the same Teams client just gets dead air when redirected to voicemail. There are no audio issues with these PSTN calls when the calls are answered so this is not a one way audio issue with the SIP etc.
This used to work just fine and I am not aware of any changes nor when it stopped working, any suggestions as to why this could be now happening?
Thanks,
Gerry
- I found it, the SBC was trying to do a SDP renegotiate of the codec when Teams transferred the call to voicemail and Teams was not happy with that so the codecs where not the same between the endpoint and the VM system hence no audio. I disabled this requirement to renegotiate and the audio is available on both ends of the call now.
Thanks for your responses guys!

Would recommend LinusCansby on this one. He has a ton of direct routing experience.
LinusCansby any reason why PSTN calls to Voicemail would suddenly stop working in a direct routing scenario? Anything in your experience you can think of?
Best, Chris
- Thanks Christopher,
We actually have a customer who is experiencing the exact same problem as us.
Gerry- Hi,
Since it something that used to work and stopped working I would suggest contacting the partner that setup your direct routing and ask them to see if there are any issues in the SBC setup. Or if you use direct routing direct from your carrier talk to them.
Most common I would say is that you don't hear the first word(s) in the greeting, that that the complete message is quiet.
