You might need to upgrade to 3.3.1 to use sdpops module: http://kamailio.org/docs/modules/stable/modules/sdpops.html

Dear List
I am trying to remove specific lines from the following original SDP body:
Content-Type: application/sdp Content-Length: 406
v=0 o=root 3048 3048 IN IP4 xxx.xxx.xxx.xxx s=session c=IN IP4 xxx.xxx.xxx.xxx b=CT:384 t=0 0 m=audio 11904 RTP/AVP 0 8 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv m=video 11602 RTP/AVP 34 99 a=rtpmap:34 H263/90000 a=rtpmap:99 H264/90000 a=sendrecv
I need to remove the following lines from the above SDP body as my International carrier does not support Video capabilities:
m=video 15042 RTP/AVP 34 99 a=rtpmap:34 H263/90000 a=rtpmap:99 H264/90000
I used the following code in Kamailio config:
if(has_body("application/sdp") && search_body("m=video")){
subst_body('#m=video ([0-9]+) RTP/AVP (.*)$# #'); subst_body('#a=rtpmap:34 (.*)$# #'); subst_body('#a=rtpmap:99 (.*)$# #'); subst_body('#a=sendrecv(.*)$# #'); }Content-Type: application/sdp Content-Length: 325 P-hint: outbound v=0 o=root 3048 3048 IN IP4 xxx.xxx.xxx.xxx s=session c=IN IP4 xxx.xxx.xxx.xxx b=CT:384 t=0 0 m=audio 11904 RTP/AVP 0 8 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv
As you can see the m=video body has been removed, however, calls are still failing. Is there something i have missed?
I am using Kamailio v3.2.2
Thanking you in advance!
