Hi, I have 2 asterisk servers link via IAX. and i'm trying to do a video call. if 2 sip users are registered on the same server, the video works fine. but if 1 sip user is on server 1 and sip user 2 on sip server 2. there's no video at all. is it because call from sip server 1 goes to sip server 2 via IAX? hope my question is clear enough, thanks in advanced Ron
