Configuring CVP for Locations-based Call Admission Control
Hairpinning
You should configure the CVP Voice Browser 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.

bearer path stays entirely within the originating gateway.
To make this configuration, enter the following command at the VB Admin command line interface.
Replace networkVRUlabelvalue with the label value that you configured in the ICM for the Type 7 VRU.

With this configuration, a call is handled as follows:
1.
