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.
Enabled Clearing this check box lets you stop sending H.235 credentials to the
external gatekeeper without deleting them.
Name The H.235 name of the Polycom RealPresence DMA system.
Password
Confirm password
The H.235 password for the Polycom RealPresence DMA system.
Algorithm Select the encryption algorithm for H.235 authentication.
LRQ test Click to test the configuration by sending an LRQ message to the external
gatekeeper.
Postliminary A postliminary is an executable script, written in the Javascript language, that
defines dial string transformations to be applied before querying the external
gatekeeper.
Enabled Lets you turn a postliminary on or off without deleting it.
Script Type (or paste) the postliminary script you want to apply. Then click Debug
this script to open the Script Debugging Dialog Box for
Preliminaries/Postliminaries and test the script with various variables.
