Field Name Values Description
Accept Any
Number
Y/N When checked, “Any Number” appears as the value in the Destination Pattern field.
The Any Number feature works differently depending on whether or not an
external routing device is used (Gatekeeper for H323 protocol, Proxy for SIP
protocol, Registrar for SPP protocol).
When no external routing device is used. If Any Number is selected, calls to phone
numbers not matching a listed Destination Pattern are directed to the IP Address in
the Add/Edit Outbound Phone Book screen. “Any Number” can be used in addition
to one or more Destination Patterns.
When external routing device is used. If Any Number is selected, calls to phone
numbers not matching a listed Destination Pattern are directed to the external
routing device used (Gatekeeper for H323 protocol, Proxy for SIP protocol, Registrar

Phone Book Configuration screen.

a non-standard protocol designed by Multi-Tech. The –SS models only support SIP

Gateway Prefix numeric This number becomes registered with the GateKeeper. Call requests sent to the
gatekeeper and preceded by this prefix are routed to the VOIP gateway.
H.323 Port
Number
1720 This parameter pertains to Q.931, which is the H.323 call signaling protocol for
setup and termination of calls (aka ITU-T Recommendation I.451). H.323 employs
only one “well-known” port (1720) for Q.931 signaling. If Q.931 message-oriented
signaling protocol is used, 1720 must be chosen as the H.323 Port Number.
