Hi,

According the RFC, it's possible to send a INVITE without any SDP.
In this case, the ACK contains the SDP after the 200 OK (with SDP) send by the callee.

In this situation, the RTP/RTCP is not dealed correclty by the media proxy and sems i.e impossible to have the audio.

Do you think this situation is possible ? The RFC can expose some case never used for example.

Do you know if the RTPProxy daemon is also concerned by this problem ?

Thanks,
Christophe
