Configuring Unified CVP H.323 Service Configuration Settings

The following sections describe some of the Unified CVP H.323 Service configuration settings
that you must make to accommodate Unified CM locations-based CAC and to minimize the
bandwidth used in your telephony solution:

•

Hairpinning

•

Call Signalling Address

You make these settings using the H.323 Service configuration and administration tool, called
VBAdmin. For detailed information about VBAdmin and its command line interface, see Chapter
9, "

," in Part 2.

Hairpinning

Configure the H.323 Service to hairpin a voice response unit (VRU) call leg to its originating
gateway. In this way, the playing of prompts does not consume WAN bandwidth and the bearer
path stays entirely within the originating gateway.

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

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.
