Install and Configure Cisco Virtualized Voice Browser
Cisco Virtualized Voice Browser (Cisco VVB) is an optional feature that provides a platform for interpreting VXML documents. Cisco VVB serves as an alternative to the use of IOS Voice Browsers (VXML gateways). When an incoming call arrives at the contact center, Cisco VVB allocates a VXML port that represents the VoIP endpoint. Cisco VVB sends HTTP requests to the Unified CVP VXML server. The Unified CVP VXML server executes the request and sends back a dynamically generated VXML document.
Cisco VVB is installed off box. Installation and configuration procedures are documented in the Installation and Upgrade Guide for Cisco Virtualized Voice Browser at https://www.cisco.com/c/en/us/support/customer-collaboration/virtualized-voice-browser/products-installation-guides-list.html.
