hi,
I configured a xlite SIP softphone version 4 on a PC with USB-video support. This phone I configured as Third Party SIP device Advanced in CUCM 8.6.
I can establish audio calls to any other phone at this CUCM, e.g. a 9971 IP phone.
But video calls doesn't work. If I call the 9971 with integrated Cisco USB camera, a normal audio call is established. Video doesn't start.
Video works proper at 9971 and xlite itself but not between this devices.
Cisco says I must used third party sip device advanced for video calls, but how it works?
Xlite use video codec H.263 and H.263+
