External Gatekeeper Device Management

Table 5-12Edit External Gatekeeper dialog box

Column	Description
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 a call to this
	gatekeeper to routed mode if:
	•	The gatekeeper is configured with a prefix.
	•	The destination signaling address in the
		gatekeeper’s location confirm (LCF) message
		contains its own IP address (indicating it’s in 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 DMA system.
Password	The H.235 password for the Polycom DMA system.
Confirm password
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.
