Cisco Cisco Customer Voice Portal 8.0(1)

This example assumes “index.jsp” is available on the VXML Server. The http keepalive method
continuously checks for availability of this document as a means to determine that the server is
capable of serving documents.

Use these CSS commands to set up the http keepalive parameters while configuring each
VoiceXML Service. Do not specify any other keepalive parameters such as frequency or retry
count. The CSS defaults of a 5-second frequency and 3 retries will be in effect. If the VXML
Server is running on an Apache Tomcat Call Server, configure the following keepalive
parameters:

keepalive type http

keepalive uri "/index.jsp"

CSS Configuration for VXML Servers: Groups

Define a group for the participating VXML Servers if your network configuration requires
source groups (see the discussion of Groups in the "General Approach" section for details).

group vxml_group1

 vip address 10.1.3.14

 add destination service CVPVoicexml1

 add destination service CVPVoicexml2

Redundancy and Failover for Unified CVP

This section describes redundancy and failover mechanisms for ASR, TTS, Media, and VXML
Servers in the Unified CVP solution.

ASR, TTS, and Media Server Redundancy for VXML Server Applications (with CSS)

If you use a CSS for ASR or TTS servers, then the IP address specified in the following ivr
commands should be the Virtual IP (VIP) address for the corresponding ASR or TTS service.
VXML Server applications rely on the gateway’s configured default for ASR and TTS servers,
which allow only a single host name or IP address to be specified for each. This differs from
the Unified CVP micro-applications based applications, which support automatic retries to
specifically named backup ASR and TTS servers.

Use the following configuration on the gateway if you are using Nuance, Scansoft, or IBM
WebSphere ASR/TTS servers:

ip host asr-en-us 10.10.10.1

ip host tts-en-us 10.10.10.2

Use the following configuration on the gateway if you are using Nuance, Scansoft, or IBM
WebSphere ASR/TTS servers:
