Hi Cisco Community, hoping to get some help on my issue.
We have a call flow that routes calls from CUCM to Microsoft Teams Voice Direct Routing (SBC) then out to PSTN. The main number is configured in CUCM as a translation pattern to translate into a new number.
(Translation pattern in CUCM routes to a number configured in Teams Admin Center which uses a VRP to route to a SBC which sends it out the the PSTN)
The call is successfully transferred to the SBC where it rings the end device. However the call is prematurely canceled before the device answers.
In the SBC logs (ribbon LX) I see a call clearing code in the SIP messages (Reason: Q.850; cause=47). I looked up the code and it refers to "codec mismatch".
How would I resolve?
Thank you in advance.
Using: CUCM 10.5.2 | SBC Ribbon | using E.164 formats
