You do realize that those param's are sofia profile params and not dialplan XML right?
Hi Brian, sure I know that. So: In sofia SIP profile I have: <param name="inbound-late-negotiation" value="true"/> <param name="renegotiate-codec-on-reinvite" value="true"/> and in my dialplan XML I hit: <action application="set" data="inherit_codec=true"/> I repeated my test scenario, sorry what I described was with inherit_codec=false. If I set inherit_codec=true (this is my purpose) sofia behavior is this: INVITE [pcma,g729] ---> FS ---> INVITE [pcma,g729] 200 OK [pcma] <--- FS ---> 200 OK [pcma] re-INVITE [g729] ---> FS Reinvite Codec Error! <--- FS Here the call is release and from the log I see that sofia just negotiatiate localy and compare the codec list in the new offer only with PCMA. With inherit_codec=false it compare the codec list with the codec loaded in the core so it match G729 (but damn it's a passthrought codec and I cannot do transcoding!). Here is an extract off the log, that show the error. Now I do not have with me the complete session log, I will send it tomorrow. Do you think it's a bug? 1970-01-01 23:10:28.600056 [DEBUG] switch_core_session.c:857 Send signal sofia/external/abcd@xyz.com [BREAK] 1970-01-01 23:10:28.600056 [DEBUG] switch_core_session.c:857 Send signal sofia/external/abcd@xyz.com [BREAK] 1970-01-01 23:10:28.620894 [DEBUG] sofia.c:5143 Channel sofia/external/abcd@xyz.com entering state [received][100] 1970-01-01 23:10:28.620894 [DEBUG] sofia.c:5154 Remote SDP: v=0 o=- 0 1 IN IP4 10.50.185.16 s=IMSS c=IN IP4 10.50.185.16 t=0 0 m=audio 10992 RTP/AVP 18 101 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 1970-01-01 23:10:28.620894 [DEBUG] sofia_glue.c:4731 Audio Codec Compare [G729:18:8000:20:8000]/[PCMA:8:8000:20:64000] 1970-01-01 23:10:28.620894 [DEBUG] sofia_glue.c:4731 Audio Codec Compare [telephone-event:101:8000:20:0]/[PCMA:8:8000:20:64000] 1970-01-01 23:10:28.620894 [DEBUG] sofia_glue.c:4845 Set 2833 dtmf send/recv payload to 101 1970-01-01 23:10:28.620894 [ERR] sofia.c:5611 Reinvite Codec Error!
