–

Enter the DNIS value that will route to Unified CVP.

–

Under Gateway/Route List, select the Gatekeeper Trunk created in the previous step.

–

In Prefix Digits (Outgoing Calls), enter the tech-prefix of Unified CVP (2#).

4. Use Device > Trunk to create a second H.225 Gatekeeper Controlled trunk. (This is the

trunk to enable outbound call routing to agents from Unified CVP to Cisco Unified
Communications Manager. )

–

Ensure that Media Termination Point required is disabled.

–

Under Gatekeeper Information:

— Select the gatekeeper that was defined in the previous step.

— Select Gateway as the Terminal Type.

— Set the technology prefix to 1#.

— Select a zone. (If left blank, Cisco Unified Communications Manager will register
to the first local zone defined in the gatekeeper.)

Unified CVP Configuration for Call Routing (tech-prefix method)

You do not need to perform specific configuration for the H.323 Service for inbound call routing
when using the tech-prefix method unless you choose to change the default tech-prefix value
of Unified CVP to some other value. You would do so using the setTechPrefix command. For
example, if there are distinct Unified CVP server farms in various geographic locations, you
might choose to route calls from one bank of gateways to a specific farm of Unified CVP servers.
In this case, you could assign 2# to one farm, 3# to the next, and so on. Unified CVP by default
will strip off the tech-prefix before passing the remainder of the DNIS to Unified ICME. The
setTechPrefixRemoval VBAdmin command can be used to prevent stripping the tech-prefix,
if so desired.

Note: Use the setTechPrefixRemoval VBAdmin command if you want to prevent stripping
off the tech-prefix.

Call Routing (zone-prefix method)

Another method of performing inbound call routing to and from Unified CVP is to use the
zone-prefix method. In this method, all H.323 devices register to the gatekeeper with the same
tech-prefix. Call routing is then determined solely on the zone-prefixes defined in the gatekeeper.

Note: The gatekeeper command show gatekeeper gw-type-prefix can be very useful in
determining how the gatekeeper will route calls based on tech-prefix.
