Hey Guys, When using mod_com_g729 I found out that FreeSWITCH is rejecting G729B in this form. I know about annexa=no parameter, however have seen quite some UAs sending it in this form. Any work-around I can make FreeSWITCH accepting it? My FreeSWITCH version: FreeSWITCH version: 1.0.head (git-) checked out somewhere in the middle of October. mod_com_g729: fsg729-167-installer Debug of such call: 2010-12-07 13:56:05.371029 [DEBUG] sofia.c:4559 Channel sofia/Ip-Switch.Net/7809163901@2.3.4.5 entering state [received][100] 2010-12-07 13:56:05.371029 [DEBUG] switch_core_state_machine.c:318 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Running State Change CS_NEW 2010-12-07 13:56:05.371029 [DEBUG] sofia.c:4570 Remote SDP: v=0 o=- 24240 28749 IN IP4 1.2.3.4 s=session c=IN IP4 1.2.3.4 t=0 0 m=audio 35892 RTP/AVP 18 4 56 a=rtpmap:18 G729B/8000 a=rtpmap:4 G723/8000 a=fmtp:4 bitrate=6.3 a=rtpmap:56 telephone-event/8000 a=ptime:30 a=nortpproxy:yes a=nortpproxy:yes a=direction:active 2010-12-07 13:56:05.371029 [DEBUG] switch_core_state_machine.c:324 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State NEW 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G729B:18:8000:30:8000]/[PCMU:0:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G723:4:8000:30:6300]/[PCMU:0:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [telephone-event:56:8000:30:0]/[PCMU:0:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4455 Set 2833 dtmf send/recv payload to 56 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G729B:18:8000:30:8000]/[PCMA:8:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G723:4:8000:30:6300]/[PCMA:8:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [telephone-event:56:8000:30:0]/[PCMA:8:8000:20:64000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4455 Set 2833 dtmf send/recv payload to 56 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G729B:18:8000:30:8000]/[G729:18:8000:20:8000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [G723:4:8000:30:6300]/[G729:18:8000:20:8000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4351 Audio Codec Compare [telephone-event:56:8000:30:0]/[G729:18:8000:20:8000] 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4455 Set 2833 dtmf send/recv payload to 56 2010-12-07 13:56:05.371029 [DEBUG] sofia_glue.c:4455 Set 2833 dtmf send/recv payload to 56 2010-12-07 13:56:05.371029 [DEBUG] switch_channel.c:2457 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Callstate Change DOWN -> HANGUP 2010-12-07 13:56:05.371029 [NOTICE] sofia.c:4776 Hangup sofia/Ip-Switch.Net/7809163901@2.3.4.5 [CS_NEW] [INCOMPATIBLE_DESTINATION] 2010-12-07 13:56:05.371029 [DEBUG] switch_channel.c:2473 Send signal sofia/Ip-Switch.Net/7809163901@2.3.4.5 [KILL] 2010-12-07 13:56:05.371029 [DEBUG] switch_core_session.c:1057 Send signal sofia/Ip-Switch.Net/7809163901@2.3.4.5 [BREAK] 2010-12-07 13:56:05.371971 [DEBUG] switch_core_state_machine.c:318 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Running State Change CS_HANGUP 2010-12-07 13:56:05.371971 [DEBUG] switch_core_state_machine.c:539 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State HANGUP 2010-12-07 13:56:05.371971 [DEBUG] mod_sofia.c:456 Channel sofia/Ip-Switch.Net/7809163901@2.3.4.5 hanging up, cause: INCOMPATIBLE_DESTINATION 2010-12-07 13:56:05.371971 [DEBUG] mod_sofia.c:518 Responding to INVITE with: 488 2010-12-07 13:56:05.371971 [DEBUG] switch_core_state_machine.c:46 sofia/Ip-Switch.Net/7809163901@2.3.4.5 Standard HANGUP, cause: INCOMPATIBLE_DESTINATION 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:539 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State HANGUP going to sleep 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:337 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State Change CS_HANGUP -> CS_REPORTING 2010-12-07 13:56:05.372880 [DEBUG] switch_core_session.c:1057 Send signal sofia/Ip-Switch.Net/7809163901@2.3.4.5 [BREAK] 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:318 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Running State Change CS_REPORTING 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:599 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State REPORTING 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:53 sofia/Ip-Switch.Net/7809163901@2.3.4.5 Standard REPORTING, cause: INCOMPATIBLE_DESTINATION 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:599 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State REPORTING going to sleep 2010-12-07 13:56:05.372880 [DEBUG] switch_core_state_machine.c:331 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) State Change CS_REPORTING -> CS_DESTROY 2010-12-07 13:56:05.372880 [DEBUG] switch_core_session.c:1057 Send signal sofia/Ip-Switch.Net/7809163901@2.3.4.5 [BREAK] 2010-12-07 13:56:05.372880 [DEBUG] switch_core_session.c:1224 Session 959 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Locked, Waiting on external entities 2010-12-07 13:56:05.372880 [NOTICE] switch_core_session.c:1242 Session 959 (sofia/Ip-Switch.Net/7809163901@2.3.4.5) Ended Ta in advance for any kind of tip!
