3CX IP PBX Windows Phone System

I tested 3CX V6 with X-Lite softphone and videoconferencing did work between internal extensions fine. 3CX does not official support video phones but since they use standards based protocols 3CX lets the video stream pass through.

 

I also understand (I didn't test it) that the Grandstream videophone also works.

 

Note:I have not tested external phone calls.
