I read that setting ‘canreinvite=yes’ in sip.conf allows direct media transfer between peers once a call is set, by sending re-INVITE messages to peers. However, When set to yes and making video calls, one of the peers at least, sometimes both are missing the video stream – no video picture, just a green background. Audio is working fine with canreinvite set to yes. Asterisk is on a public IP. Both peers are behind NAT on different networks.
I am curious to know why this is happening and if it can be fixed.
Thanks a lot,
