How to resolve the interworking for DTMF payload type 97 to payload type 101
Hi guys we have a question from a final customer regarding an issue with DTMF payload types
An IPPBX is sending DTMF under payload type 97 and SSW/GW at the core side behind SBC is waiting DTMF under payload type 101.
Could you guys please recommend the best way to configure SBC for doing such a DTMF interworking for the two VoIP entities so we can have effectively passing DTMF between them as expected?
Thank you in advance!
