Edit External Gatekeeper Dialog
Add External Gatekeeper Dialog
The following table describes the fields in the Add External Gatekeeper dialog.
Prefix Range The dial string prefix(es) assigned to this neighbor gatekeeper.
If your dial plan uses the Dial services by prefix dial rule (in the default dial
plan) to route calls to services, all dial strings beginning with an assigned
prefix are forwarded to this gatekeeper for resolution.
Enabled Indicates whether the system is using the neighbor gatekeeper.
Column Description
External Gatekeeper
Enabled Clearing this check box lets you stop using an external gatekeeper without
deleting it.
Name Gatekeeper name.
Description The text description displayed in the External Gatekeepers list.
Address Host name or IP address of the gatekeeper.
RAS port The RAS (Registration, Admission and Status) channel port number. Leave
set to 1719 unless you know the gatekeeper is using a non-standard port
number.
Prefix range The dial string prefix or prefix range for which the external gatekeeper is
responsible.
Enter a single prefix (44), a range of prefixes (44-47), multiple prefixes
separated by commas (44,46), or a combination (41, 44-47, 49).
If your dial plan uses the Dial services by prefix dial rule (in the default dial
plan) to route calls to services, all dial strings beginning with an assigned
prefix are forwarded to this gatekeeper for resolution.
If your dial plan instead uses a rule that you create to apply the Resolve to
external gatekeeper action, there is no need to specify a prefix.
Strip prefix If selected, the system strips the prefix when a call that includes a prefix is
routed to this gatekeeper.
Prefer routed If selected (the default), the system forces all calls to this gatekeeper to routed
mode.
This setting must be enabled to avoid interoperability issues with Polycom
CMA and Avaya gatekeepers, and possibly others as well.
Authentication Mode In this section, you can configure the system to send its H.235 credentials
when it sends address resolution requests to that gatekeeper.
