Version 4.4 51 March 2005
Table 5-2: Gatekeeper Parameters (continues on pages 49 to 51)
Parameter Description
Enable Pre-Grant ARQ
[EnablePregrantARQ]
Disable [0] = Disabled (default).
Enable [1] = Enables the H.323 pre-granted ARQ mechanism.
If enabled, when an endpoint registers with a Gatekeeper, the Gatekeeper can pre-grant
admission requests to that endpoint, enabling it to establish calls without applying to the
Gatekeeper for permission, thereby reducing call setup time.
Gateway Registration Type
[GWRegistrType]
Gateway registration encoding type. This defines the encoding type of the phone
numbers that is used when the gateway registers these numbers with a Gatekeeper.
You can select:
E.164 [0] (default)
H323-ID [1]
E.164 and H323-ID [2]
NPI/TON from Table [3]
NPI/TON and H323-ID [4]
For detailed information on the available methods the MP-1xx gateway registers with a
Gatekeeper refer to Section
8.2 on page 152.
For detailed information on the Registration Prefixes Table refer to Section 5.8.6 on
page 88.
Register as Terminal
[IsTerminal]
No [0] = Gateway registers and acts as a standard gateway (default).
Yes [1] = Gateway registers as an H.323 terminal with multiple aliases (up to 24 for
MP-124). In all gateway messages, the terminal type value is set to terminal.
Timers
Registration Time [sec]
[RegistrationTime]
Time in seconds between registrations to the Gatekeeper.
The default Registration Time is 60 seconds.
Note: This setting must match the configuration settings on your Gatekeeper.
RAS Response Timeout [sec]
[ResponseTimeOut]
Time in seconds that the gateway waits for a RAS response from the Gatekeeper. When
this time expires, the gateway retransmits the RAS message.
The range is 0 to 2 0. The default time is 1 second.
Number of RAS
Retransmission
[MaxRetries]
Number of times that the gateway retransmits the RAS message to the Gatekeeper,
before the gateway
determines that the Gatekeeper is not responding.
If you have enabled Gatekeeper Redundancy, the gateway tries the next Gatekeeper. If
none of the Gatekeepers are responding and you have enabled Fallback to internal
routing, the gateway starts using the internal Tel to IP Routing table.
The default number of retransmissions is 6.
Note: This setting must match the configuration settings on your Gatekeeper.
Time between Gatekeeper
Retries [sec]
[TimeBetweenGKsLoops]
Time in seconds before the gateway tries to contact the list of Gatekeepers again.
The default time is 60 seconds.
Note: This setting must match the configuration settings on your Gatekeeper.
