Hello all, I've the situation that some SIP-endpoints do require an explicit payload for the stream (this probably due to badly implemented jitter-buffer ...). My observation is that the ptime value (e.g. "a=ptime:40") seems to be ignored by PJMedia. Next scenario is valid in my situation: PJSIP <---> 'Weird' SIP-endpoint <--- INVITE w/h SDP ---> TRYING ---> RINGING ---> 200-OK with SDP (with G711u+a, telephone event, no ptime) <--- ACK with SDP (selecting G.711-aLaw and includes a=ptime:40) Now I see PJSIP receives a RTP-stream with 40ms payload, but PJSIP itself is sending with 20ms payload. I've already tried some options which I found during a search, but they all failed or had side effects. Question: How do I make PJSIP/PJMedia obey the ptime value in the SDP-Answer?
