Hello together
I am new here and hope someone of you can help me.
ACTUAL state:
Telephony via Mitel MiVoice 400
TARGET state:
Use Mitel MiVoice 400 + audiocodes SBC for Teams telephony.
Problem:
Mitel: 172.16.4.10
Audiocodes: 172.16.4.11
When a call is placed to my internal/external number, the call also rings successfully on my Teams (recorded as an additional mobile device) account. Unfortunately, no voices can be heard on either side. The syslos on the part of audiocodes gives the following information

Does anyone have an idea what is not working here? Unfortunately, I can't find any precise information from Mitel either. The Audiocodes specialist thinks that it should work...
In addition, it should be mentioned that no call can be made on the part of Teams. However, I think this is a different problem.
I would be very happy to receive a reply.
Currently I'm a bit lost because all suppliers say it should work and I can't find any current information from Mitel on what exactly the system expects.
Kind regards
