Does opensips support for video call ? how can I run it?
By the way,Is GNU version 2 free ?
OpenSIPS is a SIP proxy, so it does not care about the media part (audio, FAX, video, files, etc) - the media goes directly between the clients, so if the clients support video, it will work transparently for OpenSIPS.
Short answer: it works :) and it is free.
