Figures 3-14 through 3-16 show how to implement gatekeeper-controlled intercluster
trunks (an H.225 trunk or a gatekeeper-controlled intercluster trunk) in CUCM. The steps
are as follows:
Step 1 Choose Device > Gatekeeper and click Add New. In the Gatekeeper
Configuration window, shown in Figure 3-14, enter the IP address of the
H.323 gatekeeper and optionally a description. Then make sure that the
Enable Device check box is checked.
Step 2 After you have configured the gatekeeper, you can add the gatekeepercontrolled
trunk, as shown in Figure 3-15. Choose Device > Trunk and
click Add New. Then choose the trunk type. As discussed earlier in this
chapter, there are two types of gatekeeper-controlled H.323 trunks.
Gatekeeper-controlled intercluster trunks must be used when connecting
to CUCM earlier than version 3.2. H.225 trunks are used to connect to
CUCM version 3.2 or higher, as well as other H.323 devices such as
gateways or conferencing systems.

Chapter 3: Implementing Multisite Connections
Step 3 After selecting the trunk type, enter a name for the trunk, choose the
device pool that should be used, and optionally enter a description.
Step 4 As shown in Figure 3-16, you must provide the gatekeeper information.
From the drop-down list, choose the gatekeeper that this trunk should
register to, and then choose the terminal type. CUCM can register trunks
as terminals or gateways with an H.323 gatekeeper. Usually the terminal
type is set to Gateway.
Figure 3-16 Implementing CUCM Gatekeeper-Controlled Intercluster Trunk Configuration.
Steps 4 Through 6
Choose previously
configured gatekeeper.
Trunks can register as terminal
or gateway with the gatekeeper.
Choose terminal type gateway.
Enter the gatekeeper zone in which
the trunk should be registered.
Enter the prefix that should be
registered with the gatekeeper.
Step 5 In the Technology Prefix field, enter the prefix, which should be
registered with the gatekeeper.
NOTE The Prefix DN you enter is the prefix that the trunk will register with the
gatekeeper. It can, but does not have to, include a Technology Prefix. In Figure 3-16, a
Technology Prefix of 408 is used. More information about prefixes and technology
prefixes is provided in Cisco Voice over IP (CVOICE), Third Edition.
Step 6 Enter the gatekeeper zone in which the trunk should be registered.
References
TIP The H.323 zone name is case-sensitive. Make sure that it matches the zone name
that was configured at the gatekeeper. In addition, if the zone name is not added and no
zone security is set up, CUCM registers into the first configured zone on its assigned
gatekeeper, which could cause problems.
