No it is NOT mandatory to include them. Only when they are on defined codec numbers. /b On Jun 2, 2010, at 9:14 AM, Mark Campbell-Smith wrote:
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?
