[Serusers] Does This rtpproxy Output Look Correct?

Hi All. I'm using -dev21 with rtpproxy/nathelper. I do have everything working except I'm fighting a problem where some ATAs get disconnected after re-INVITEs are sent. Can anyone tell me if these two RTPproxy output sequences look correct? The first one is from a Grandstream BT100 dialing a PSTN phone. The second one is a PSTN phone dialing my Grandstream BT100. I don't understand why I receive re-INVITEs when dialing SIP->PSTN but not when dialing PSTN->SIP. Does anyone know why CASE 2 below shows an RTP entry and an RTCP entry whereas CASE 1 only shows an RTP entry and why do I not see the rtpproxy timer being restarted in CASE 2? Could this have anything to do with the type of firewall (symeteric or not)? I started rtpproxy with "-2f" on the command line. CASE 1) SIP->PSTN rtpproxy: rtpproxy started, pid 10478 rtpproxy: new session 096b464ff0c33897(a)172.16.1.34, tag ad34d40914233c7f requested rtpproxy: new session on a port 35000 created, tag ad34d40914233c7f rtpproxy: pre-filling caller's address with 66.90.50.230:5004 rtpproxy: lookup on a ports 35000/35002, session timer restarted rtpproxy: pre-filling callee's address with 216.229.127.60:11946 rtpproxy: callee's address filled in: 216.229.118.100:11946 (RTP) rtpproxy: lookup on a ports 35000/35002, session timer restarted rtpproxy: lookup on a ports 35000/35002, session timer restarted rtpproxy: lookup on a ports 35000/35002, session timer restarted (<==re-INVITE received here) rtpproxy: lookup on a ports 35000/35002, session timer restarted CASE 2) PSTN->SIP rtpproxy: new session 1976507-3311294543-619870(a)66.243.109.99, tag 705F8840-221C requested rtpproxy: new session on a port 35004 created, tag 705F8840-221C rtpproxy: pre-filling caller's address with 216.229.127.60:18988 rtpproxy: lookup on a ports 35004/35006, session timer restarted rtpproxy: pre-filling callee's address with 66.90.50.230:5004 rtpproxy: caller's address filled in: 66.236.245.98:18988 (RTP) rtpproxy: caller's address filled in: 66.236.245.98:18989 (RTCP) Regards, Paul __________________________________ Do you Yahoo!?
