Setting H. 323 Account/H.323 IP Call
The H.323 protocol is enabled by default. You can place IP calls via the 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 you via your H.323 name or the extension instead of the IP address.
