Re: [Serusers] Anyway to steal Media IP/Port from RTPProxy or MediaProxy

Dear Greger & List Actually, I want Asterisk to deploy re-INVITE to let the media flow directly between my UAs and ITSPs (neither relay via RTP/MediaProxy and Asterisk RTP). Case 1: If I forward it to Asterisk and use re-INVITE in sip.conf exten => _X.,1,Answer() exten => _X.,2,Dial(SIP/Number@ITSP <mailto:SIP/Number@ITSP>) exten => _X.,3,Hangup Asterisk actually open RTP with UAs and have the c=/m= info because of Answer. But I faced the re-INVITE with call drop-off issue. When both parties are talking, if remote phone from ITSP hang up, things are fine. If UA hang up, remote phone is still in talking status, and I see no BYE from Asterisk send to ITSP, even it receive BYE from UA Case 2: If I forward it to Asterisk and not use re-INVITE in sip.conf exten => _X.,1,Answer() exten => _X.,2,Dial(SIP/Number@ITSP <mailto:SIP/Number@ITSP>) exten => _X.,3,Hangup Everything is fine Case 3: If I forward it to Asterisk and use re-INVITE in sip.conf exten => _X.,1,Dial(SIP/Number@ITSP <mailto:SIP/Number@ITSP>) exten => _X.,2,Hangup Asterisk don't actually open RTP with UAs and don't have the c=/m= info. At that time, c= and m= from UAs to Asterisk always point to RFC1918, and also in Asterisk's memory knowledge. If this case, when re-INVITE happen, the re-INVITE to ITSP contain RFC1918 IP, and cause wrong media path.
