Thanks Brian. I didnt think it was mandatory. As my client is not accepting this sdp format, can I change it? I've tried with <action application="export" data="codec_string=PCMA,PCMU"/> and <action application="export" data="absolute_codec_string=PCMA,PCMU"/> and <action application="export" data="sip_append_audio_sdp=a=rtpmap:8 PCMA/8000"/> <action application="export" data="sip_append_audio_sdp=a=rtpmap:0 PCMU/8000"/> and have late negotiation active, but nothing is changed in the SDP. Basically I want change v=0 o=Sippy 142967340 3687727620696226321 IN IP4 80.232.37.178 s=- t=0 0 m=audio 36824 RTP/AVP 8 0 18 101 c=IN IP4 213.50.91.3 a=fmtp:18 annexb=yes a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sqn: 0 a=cdsc: 1 audio RTP/AVP 8 a=cdsc: 2 image udptl t38 a=cpar: a=T38FaxUdpEC:t38UDPRedundancy a=cpar: a=T38FaxVersion:0 a=cpar: a=T38MaxBitRate:14400 to something like: v=0 o=Sippy 142967340 3687727620696226321 IN IP4 80.232.37.178 s=- t=0 0 m=audio 36824 RTP/AVP 8 0 18 101 c=IN IP4 213.50.91.3 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 Is there an 'easy' way to do this?

No it is NOT mandatory to include them. Only when they are on defined codec numbers.

Coming back to my original question: Is it mandatory to always include the rtpmap details for PCMU/PCMA codes? For example something like 'a=rtpmap:8 PCMA/8000' and 'a=rtpmap:0 PCMU/8000'?
Is it possible to add the end of the SDP parameters by doing something like: <extension name="fix_phonzo" continue="true"> <condition field="caller_id_number" expression="123456"> <action application="export" data="sip_append_audio_sdp=a=rtpmap:8 PCMA/8000"/> <action application="export" data="sip_append_audio_sdp=a=rtpmap:0 PCMU/8000"/> </condition> </extension>
Can this be done anywhere in the dialplan as long as its before the bridge command?
