Step 3 Router(config-gk)# zone prefix gatekeeper-name
e164-prefix [blast | seq] [gw-priority priority
gw-alias [gw-alias, ...]]
Adds a prefix to the gatekeeper zone list.
The keywords and arguments are as follows:
• 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-priority priority gw-alias—(Optional) Use
the gw-priority option 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-alias for
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-alias name 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.
