Hi, I am facing terrible issue regarding no audio/voice on both sides. I am using g729 codec on two machines and carrier also supports g729 codec. I can see the RTP traffic flowing but there is no audio. Call is going from Server 1 to Server 2. I can see the established SIP channels on Server but still no audio C.L.M.37 = Global Address **-Server-1* X.Y.X.55 = LAN Address of **-Server-1* M.G.W.23 = Media Gateway of Carrier A.B.C.136 = Global Address **-Server-2* **-Server-1* codec and format used: codec_g729.so format_g729.so 126.475451 X.Y.X.55 -> M.G.W.23 RTP Payload type=ITU-T G.729, SSRC=1224682667, Seq=171, Time=171288 126.495804 A.B.C.136 -> C.L.M.37 RTP Payload type=ITU-T G.729, SSRC=1406269818, Seq=17753, Time=171608 126.495833 X.Y.X.55 -> M.G.W.23 RTP Payload type=ITU-T G.729, SSRC=1224682667, Seq=172, Time=171448 126.515405 A.B.C.136 -> C.L.M.37 RTP Payload type=ITU-T G.729, SSRC=1406269818, Seq=17754, Time=171768 126.515435 X.Y.X.55 -> M.G.W.23 RTP Payload type=ITU-T G.729, SSRC=1224682667, Seq=173, Time=171608 126.535204 A.B.C.136 -> C.L.M.37 RTP Payload type=ITU-T G.729, SSRC=1406269818, Seq=17755, Time=171928 126.535423 X.Y.X.55 -> M.G.W.23 RTP Payload type=ITU-T G.729, SSRC=1224682667, Seq=174, Time=171768 126.555461 A.B.C.136 -> C.L.M.37 RTP Payload type=ITU-T G.729, SSRC=1406269818, Seq=17756, Time=172088 126.555579 X.Y.X.55 -> M.G.W.23 RTP Payload type=ITU-T G.729, SSRC=1224682667, Seq=175, Time=171928 **-Server-2* Codec used : codec_g729-ast12-gcc4-glibc-x86_64-pentium4.so 101.374796 A.B.C.136 -> C.L.M.37 RTP PT=ITU-T G.729, SSRC=0x53D1F97A, Seq=17785, Time=176728 101.389644 213.166.5.134 -> A.B.C.136 RTP PT=ITU-T G.729, SSRC=0x15130586, Seq=55472, Time=879827237 101.389665 A.B.C.136 -> C.L.M.37 RTP PT=ITU-T G.729, SSRC=0x53D1F97A, Seq=17786, Time=176888 101.409653 213.166.5.134 -> A.B.C.136 RTP PT=ITU-T G.729, SSRC=0x15130586, Seq=55473, Time=879827397 101.409674 A.B.C.136 -> C.L.M.37 RTP PT=ITU-T G.729, SSRC=0x53D1F97A, Seq=17787, Time=177048 101.429709 213.166.5.134 -> A.B.C.136 RTP PT=ITU-T G.729, SSRC=0x15130586, Seq=55474, Time=879827557 101.429723 A.B.C.136 -> C.L.M.37 RTP PT=ITU-T G.729, SSRC=0x53D1F97A, Seq=17788, Time=177208 101.454956 213.166.5.134 -> A.B.C.136 RTP PT=ITU-T G.729, SSRC=0x15130586, Seq=55475, Time=879827717 Any one has any idea why it is behaving so. /ag -------------- next part -------------- An HTML attachment was scrubbed...
