Instructions for Configuring Speech Software for Cisco Unified
Contact Center Express and Cisco Unified IP IVR 7.0

PB 546866

Cisco

Unified Contact Center Express and Cisco Unified IP Interactive Voice Response (IP IVR) 7.0 use

the Media Resource Control Protocol (MRCP) to enable them to interoperate in a standardized way with

speech vendors that implement MRCP. However, each vendor imposes its own variations within the limits

of the standards. Therefore, specific vendor software may not interoperate with Cisco Unified Contact

Center Express and Cisco Unified IP IVR 7.0 without additional configuration.

In addition, Cisco has validated only four speech products for this purpose so far: Nuance Speech Server (NSS),

Nuance SpeechWorks MediaServer (SWMS), Nuance MRCP 1.0, and IBM WebSphere Voice Server.

Configuration

This bulletin describes the additional items that must be configured for each of the vendor’s software after it is

installed for it to interoperate with Cisco Unified Contact Center Express and Cisco Unified IP IVR 7.0. It is assumed

that the software has been installed according to the vendor’s instructions.
