MultiVoice Gateway for the MAX— User’s Guide
Preliminary November 23, 1998
6-3
When an IP address is not assigned to 2nd GK IP, then the MultiVoice Gateway goes into a
slow poll mode with the MultiVoice Access Manager at GK IP Adrs. The MultiVoice Gateway
attempts registrations with the MVAM at GK IP Adrs at 30-second intervals. During the time
the Gateway is unregistered, new calls are blocked, which means the MultiVoice Gateway will
reject any new calls.
Note:
Anytime a MultiVoice Gateway is attempting to register with a Gatekeeper, the
Gateway is effectively unregistered with any Gatekeeper. During this period calls are blocked.
However, existing calls continue to operate normally.
Controlling keep-alive registration
Once registered with a Gatekeeper, a MultiVoice Gateway re-registers with its currently
registered Gatekeeper every 120 seconds. This is called the keep-alive registration. The
Keepalive Timer parameter sets the time interval between attempts to reregister with a system
running the MultiVoice Access Manager following the initial registration. This value equals
the wait time, in seconds, between each attempt to re-register.
You may enter any value between 1 and 65535. Changes to the Keepalive Timer parameter
become effective with the next registration cycle.
When the keep-alive registration fails, a MultiVoice Gateway does the following:
•
If valid IP addresses (non-null) are configured for both GK IP Adrs and 2nd GK IP, the
MultiVoice Gateway attempts to register with the MultiVoice Access Manager at the 2nd
GK IP address. Once it successfully registers with the secondary Gatekeeper, the
MultiVoice Gateway is operating in backup mode.
•
If the IP address for 2nd GK IP is null, then the MultiVoice Gateway goes into a slow poll
mode with the MultiVoice Access Manager at GK IP Adrs.
Reregistration policy parameters
After a MultiVoice Gateway registers with the MultiVoice Access Manager at 2nd GK IP, it
periodically attempts to reregister with the MultiVoice Access Manager at GK IP Adrs. These
attempts to reregister with the primary Gatekeeper are initiated after every cycle of five
successful registrations with the secondary Gatekeeper. If the Gateway cannot register with the
primary Gatekeeper in this mode, it performs keep-alive registration with the secondary
Gatekeeper.
The Reg Retries parameter sets the number of attempts a MultiVoice Gateway will make each
time it executes keep-alive registration. Since a Gateway may not successfully register on its
first attempt, the value for this parameter represents the number of repeated registration
attempts a Gateway makes during a registration cycle, until it either registers successfully or
until all attempts have failed. You may enter any value between 1 and 200 for Reg Retries.
Changes to this value become effective with the next registration cycle. This value defaults to
5 attempts.
The Reg Retry Timer parameter sets the time interval between each registration attempt with a
MultiVoice Access Manager. This sets the pause, in seconds, between each registration attempt
specified by the Reg Retries parameter. You may specify a time between 1 and 200 seconds.
Changes to this value become effective with the next registration cycle. This value defaults to
5 seconds.
