Dear Colleagues,
I have setup an Audiocodes VE Direct Routing SBC, but during the tests I noted that I was not able to forward calls. As I can see, during the REFER process there is a 488 Not Acceptable answer, because of media mismatch between the Mediant and the O365. The p2p calls are working properly in every direction.
Have you experienced this kind of problem?
I have attached the SIP log (in .xlsx format, since .txt is not allowed), and the participants are:
10055 – Teams (Transferor)
20055 – CUCM registered phone (Transferee)
80000 – Mediant registered phone (Transfer target)
Thanks,
Laszlo

@Henry Morales In which option of the configuration did you make the adjustment?

@Cristian Arguello this was setup on the AC SBC > SIP Trunk IP Profile > SBC Forward and Transfer.
Remote REFER Mode = Handle Locally
Remote Replaces Mode = Handle Locally
Remote 3xx Mode = Handle Locally

Hi @Henry Morales, Audiocodes suggests creating a special SBC Routing rule in the IP-2-IP section, too.
Check the official manual on page 40
