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.
