Minimize bandwidth usage on the WAN

This section also describes other call flow and bandwidth utilization issues to consider.

The following sections do not include detailed installation and configuration instructions. Rather,
they are intended to provide you with guidance as you set up the Unified CVP solutions in your
network. For additional information about how to install, set up, run, and administer Unified
CVP, refer to

Configuring Unified CM Service Configuration Settings

Set the following configuration parameters to make Unified CM use the Ingress gateway instead
of Unified CVP as the originating location of the call.

•

Set "Accept Unknown TCP connection" in Unified CM Service parameters.

•

Set the Unified CM Service parameter "GK controlled trunk that will listen to 1720" to
“None”.

•

Do not define Unified CVP as a gateway device in Cisco Unified Communications Manager.

•

Define the Ingress gateway(s) as gateway devices in Unified CM. Assign the correct location
to the device(s).

These settings will ensure that CAC can be properly adjusted based on the locations of the
calling endpoint and the phone.

Configuring Ingress Gateway H.323 Settings

To help the Unified CVP H.323 Service identify the Unified CM cluster the Ingress gateway
is registered to, a translation rule on the Ingress gateway is used. The rule will prefix a digit to
the called number prior to initiating the call set-up to Unified CVP. The prefixed digits represent
the tech-prefix number used by the Unified CM Cluster gatekeeper controlled trunk when
registering with the gatekeeper.
