I am trying to achieve something similar to that : http://wiki.freeswitch.org/wiki/Codec_negotiation#Modifying_the_codec_when_u... but I am using xml_curl to create the dialplan (i.e. the web server that serves the dialplan makes the decision about the SDP). So I need a way to write the new SDP in the XML dialplan response. However, in the above example due to the regex manipulation the user is not facing the problem that I am with setting the switch_r_sdp to a complex value that contains =, spaces, new lines etc. Brian West wrote:
Why are you needing to rewrite it?

Let's say I have:
v=0 o=- 1258463684 1258463684 IN IP4 xxx.xxx.xxx.xxx s=Opal SIP Session c=IN IP4 xxx.xxx.xxx.xxx t=0 0 m=audio 5144 RTP/AVP 18 3 101 120 c=IN IP4 xxx.xxx.xxx.xxx a=rtpmap:18 G729/8000/1 a=fmtp:18 annexb=no a=rtpmap:3 gsm/8000/1 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16,32,36 a=rtpmap:120 NSE/8000 a=fmtp:120 192-193
who to I set the switch_r_sdp variable in xml?
Obviously this doesn't work :
<action application="set" data="switch_r_sdp=v=0 o=- 1258463842 1258463842 IN IP4 xxx.xxx.xxx.xxx s=Opal SIP Session c=IN IP4 xxx.xxx.xxx.xxx t=0 0 m=audio 5148 RTP/AVP 18 3 101 120 c=IN IP4 xxx.xxx.xxx.xxx a=rtpmap:18 G729/8000/1 a=fmtp:18 annexb=no a=rtpmap:3 gsm/8000/1 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16,32,36 a=rtpmap:120 NSE/8000 a=fmtp:120 192-193 "/>
Do I have to escape any special characters and how? I tried using escaped quotes, escaped spaces, escaped tabs etc. Nothing worked.
Any suggestions?
