Specifies the port number for connectionless tunneling

features. (For more information about these
features, refer to the relevant sections of the Hybrid
IP-PBX documentation.)
• If you are using a gatekeeper, and "Routed" is
specified for the parameter Call Signaling Model

cannot use the enhanced networking features.
