I am trying to achieve something similar to that : http://wiki.freeswitch.org/wiki/Codec_negotiation#Modifying_the_codec_when_using_proxy_media_mode
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? > > /b > > On Nov 17, 2009, at 7:42 AM, Apostolos Pantsiopoulos wrote: > > >> I am trying to use switch_r_sdp to rewrite the SDP. >> The problem I am facing has to do with the way of doing 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? >> >> >> >> >> -- >> ------------------------------------------- >> Apostolos Pantsiopoulos >> Kinetix Tele.com R & D >> email: [email protected] >> ------------------------------------------- >> >> _______________________________________________ >> FreeSWITCH-users mailing list >> [email protected] >> http://lists.freeswitch.org/mailman/listinfo/freeswitch-users >> UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch- >> users >> http://www.freeswitch.org >> > > > _______________________________________________ > FreeSWITCH-users mailing list > [email protected] > http://lists.freeswitch.org/mailman/listinfo/freeswitch-users > UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users > http://www.freeswitch.org > _______________________________________________ FreeSWITCH-users mailing list [email protected] http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
