Hi Anupama ; Unfortunately your sdp is not correct.. I guess you repeated all the audio codecs for video line.. try to separate m "pjmedia_sdp_media" into two.. i did it like that.. i created maudio and mvideo .. Also you assigned the same port number.. you can assign +2 of audio port number to video.. Pjsip opens 8 sockets when it initialized.. so 4002 will be suitable to be used for video.. Below is my sdp .. I am only using G711 codecs right now. v=0 o=- 3436101648 3436101649 IN IP4 192.168.0.220 s=pjmedia c=IN IP4 192.168.0.220 t=0 0 a=X-nat:0 m=audio 4000 RTP/AVP 0 a=rtpmap:0 PCMU/8000 m=video 4002 RTP/AVP 96 a=rtpmap:96 H264/90000 a=recvonly Regards Muge On Fri, Nov 21, 2008 at 6:39 AM, piyumali pathirage <piyumali2004 at yahoo.com>wrote: > Hi, > I hope to use PJSIP sip stack to the soft phone that I'm implementing.
