Hi all, I am having trouble with FreeSwitch handling late codec negotiation for video calls. The call logs are here: http://pastebin.freeswitch.org/15481 I have this line: <param name="enable-3pcc" value="proxy"/> added to the external sip_profile for handling late codec negotiation. I also have <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA,H263"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,H263"/> in vars.xml for codec support list. The initial INVITE contains no SDP for the caller and once the callee answers the call, it sends the 200 OK with audio (pcma, pcmu) and video (H263) codec capabilities. FreeSwitch forwards the 200 OK to the caller without video codec capabilities. As a result, the video call does not establish properly. Could someone give me a pointer? Thanks, George
