Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

 

Command

Purpose

 

 

 

Step 3 Router(config-gk)# zone prefix gatekeeper-name

Adds a prefix to the gatekeeper zone list.

 

e164-prefix[blast seq] [gw-priority priority

The keywords and arguments are as follows:

 

gw-alias [gw-alias, ...]]

 

 

• gatekeeper-name—Specifies the name of a local

 

 

or remote gatekeeper, which must have been

 

 

defined by using the zone local or zone remote

 

 

command.

 

 

• e164-prefix—Specifies an E.164 prefix in

 

 

standard form followed by dots (.). Each dot

 

 

represents a number in the E.164 address. For

 

 

example, 212....... is matched by 212 and any 7

 

 

numbers.

 

 

Note Although a dot to represent each digit in an

 

 

E.164 address is the preferred configuration

 

 

method, you can also enter an asterisk (*) to

 

 

match any number of digits.

 

 

• blast—(Optional) If you list multiple hopoffs,

 

 

indicates that the location requests (LRQs)

 

 

should be sent simultaneously to the gatekeepers

 

 

based on the order in which they were listed. The

 

 

default is seq.

 

 

• seq—(Optional) If you list multiple hopoffs,

 

 

indicates that the LRQs should be sent

 

 

sequentially to the gatekeepers based on the

 

 

order in which they were listed. The default is

 

 

seq.

 

 

• gw-prioritypriority gw-alias—(Optional) Use

 

 

the gw-priorityoption to define how the

 

 

gatekeeper selects gateways in its local zone for

 

 

calls to numbers that begin with prefix

 

 

e164-prefix. Do not use this option to set priority

 

 

levels for a prefix assigned to a remote

 

 

gatekeeper.

 

 

Use values from 0 to 10. A 0 value prevents the

 

 

gatekeeper from using the gateway gw-aliasfor

 

 

that prefix. Value 10 places the highest priority

 

 

on gateway gw-alias. If you do not specify a

 

 

priority value for a gateway, the value 5 is

 

 

assigned.

 

 

To assign the same priority value for one prefix

 

 

to multiple gateways, list all the gateway names

 

 

after the pri-0-to-10 value.

 

 

The gw-aliasname is the H.323 ID of a gateway

 

 

that is registered or will register with the

 

 

gatekeeper. This name is set on the gateway with

 

 

the h323-gateway voip h.323-id command.
