Cisco Cisco Customer Voice Portal 8.0(1)

where you replace NetworkRoutingNumber with the label value that you configured in Unified
ICME with the Type 3, 7, or 10 VRU.

Note: This command takes effect immediately. You do not need to restart the H.323 Service.

With this configuration, a call is handled as follows:

1. When the H.323 Service receives a call, it notifies Unified ICME that a call has arrived.

2. Unified ICME might return a transfer request to Unified CVP that instructs Unified CVP

to send a second call (the VRU call leg) to an IOS Voice Browser for prompt and collect
treatment.

3. When Unified CVP receives the transfer request, it sends an admission request (ARQ) to

the gatekeeper, but it ignores the reply and instead sends the VRU call leg back to the
originating gateway.

Call Signaling Address

Configure the H.323 Service to transfer calls to accommodate the Unified CM locations-based
CAC.

To make this configuration, enter the following command at the VBAdmin command line
interface:

Note: This command takes effect immediately. You do not need to restart the H.323 Service.

With this configuration:

•

The H.323 Service forces the H.225 SETUP message to the Unified CM port 1720, which
is the default H.225 listening port.

•

The H.323 Service includes the IP address of the originating gateway in the ARQ and in the
H.225 SETUP message that it sends to Unified CM.

In this way, Unified CM will identify calls as originating from the remote gateway instead of
from Unified CVP and will adjust its CAC counters accordingly.

Unified CVP Bandwidth Utilization

The following factors contribute to WAN bandwidth usage by Unified CVP in a Centralized
Call Control with Distributed Queuing call flow model:
