The URL configured by the above ivr commands defines the gateway's default target for ASR
and TTS services, and is in effect for all calls handled by that gateway. You can override it
dynamically in your VXML Server application by populating the Cisco-proprietary VoiceXML
properties "com.cisco.asr-server" or "com.cisco.tts-server."

Media servers require no special gateway configuration to work with a CSS for automatic
failover.

ASR, TTS, and Media Server Redundancy for Micro-app-based Applications (without CSS)

If you do not use a CSS for ASR or TTS servers, the IVR Service plays a significant role in
implementing a failover mechanism for Media Servers, ASR/TTS Servers and micro-app-based
applications. Up to two of each such servers are supported, and the IVR Service orchestrates
retries and failover between them.

• This redundancy mechanism is only available for Unified CVP micro-applications.

• For information about setting up the IVR Service to accommodate failover, refer to the

Operations Console online help.

About the IVR Service Failover Mechanism

The IVR Service failover mechanism applies to:

•

Connections between the IVR Service and the IOS Voice Browser, only.

Note: Unified CVP H.323 Service has its own failover mechanism for Media Server and
does not communicate with an ASR/TTS Server.

•

All communication between the IOS Voice Browser and an ASR Server, TTS Server, or
Media Server. For ASR/TTS Servers, the failure mechanism is only useful if a CSS is not
configured for the gateway aliases: 

 and
