PJSIP and h264 video not working

Does pjsip support video on this platform, I have Fanvil video door phones on pjsip with h264 codec on both the intercom & vitalpbx, they have audio but no video, if I change the extension device to sip I get audio & video. Is this a known issue or do I just have configuration errors ?

Share your PJSIP Settings and the settings of the Devices involved in this issue.
