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.

LRQ test 
Click to test the configuration by sending an LRQ message to the external

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.
