Configuring H.323 Settings
Yealink VC400/VC120 video conferencing systems support H.323 protocol. If your network uses
a gatekeeper, you can register an H.323 account for the system, and specify its H.323 name and
extension. This allows others to call the system by entering the H.323 name or extension instead
of the IP address.
SIP settings parameters on the system are described below:
