Cisco VVB Introduction

Cisco Virtualized Voice Browser (VVB) is designed to facilitate concurrent multimedia communication processing.

Cisco VVB has the following features:

  • Facilitates self-service options such as access to check account information or user-directed call routing by processing user commands through touchtone input or speech-recognition technologies.

  • Allows customers to retrieve the required information through voice commands without interacting with an agent, to navigate to the correct department, or to get help from an agent.

  • Provides multilingual support for Cisco VVB server prompts for automated speech recognition (ASR) and text-to-speech (TTS) capabilities.

  • Provides more comprehensive and effective customer service by efficiently handling call traffic with self-service or fast transfer to the correct agent the first time.

Cisco VVB Web Interfaces

You can use a web browser to administer Cisco VVB. Cisco VVB provides the following two web interfaces:

  • Cisco VVB Serviceability—Use this web interface to view alarm and trace definitions for Cisco VVB services, start and stop engine, monitor engine activity, and so on.
