Cisco Cisco Unified Customer Voice Portal 11.0(1)

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:

•

•

•

The following sections describe the bandwidth requirements of these factors in an example
Centralized Call Control with Distributed Queuing call flow model. The examples in these
sections are based on data that Cisco obtained from testing.

In these examples, assume that:

•

Each call begins with some IVR treatment followed by a transfer to an agent.

•

Each branch has 20 agents and each agent handles 30 calls per hour. Thus, the total number
of calls is:

20 * 30 = 600 calls per hour = 0.166 calls per second (CPS).

VoiceXML Documents

A VoiceXML document corresponds approximately to a Run External node in a Unified ICME
script.
