Prevent calls from
unregistered endpoints:
In the LRQ Size area, you can limit the number of source aliases in a
forwarded LRQ message to a maximum of two to allow interoperability with
gatekeepers that cannot handle more than two source aliases.
In the Default Alias area, you can specify a default alias to be added to incom-
ing calls without a destination message in the Q.931 Setup message. This alias
allows the embedded gatekeeper or a LAN/Subscriber-side gatekeeper to
route the call to a default endpoint. Enter a default alias and select one of the
following types:
• E.164
• H.323
In the Stale Time area, you can arrange to delete clients that have not sent any
registration requests for the specified interval. This area includes the
following configurable parameters:

Description

Select the checkbox if the gatekeeper has been deployed
with multiple outbound proxies and must decide which
proxy to use based on the IP address returned in the LCF.
This is an advanced configuration option and should
usually not be selected.
Description
Enter a time in seconds. This setting controls how
long an endpoint's registration should be valid. At
the end of this period the endpoint sends another
registration request.
Blocks unregistered LAN-side endpoints from
making calls through the device.
