Call Protocol
The VC800 video conferencing system supports SIP and H.323 call protocols. H.323 is commonly
used to communicate to other video conferencing systems. SIP is commonly used to
communicate with other VoIP devices. You can configure which protocol is to be used when the
system is making calls. When the Auto call protocol is used, the system preferentially uses the
H.323 protocol to place calls. If there is no available H.323 account on the system, the system
will switch to the SIP protocol. You can also specify the desired protocol for the system to place
calls via the remote control or web user interface.
