Cisco Cisco Unified Customer Voice Portal 11.0(1)

Note: Services must be activated before they are available to be used.

The following two services represent two VXML Servers that can be accessed for VoiceXML
documents.

CSS Configuration for VXML Servers: Content Rule

Using the content owner you have defined, define a content routing rule for the VoiVXMLceXML
Servers. CSS offers many load balancing types for choosing an active VXML Server. This
application uses the default defined round-robin as the balancing method. Additionally, once
the VXML Server is chosen for the call, the CSS will use an internally generated cookie to
guarantee that all future VoiceXML requests in that call use the same VXML Server.

CSS Configuration for VXML Servers: Keepalive Method

For VXML Servers, use the http keepalive method. This ensures that the CSS determines the
availability of a server at the application layer. In order to implement this keepalive method,
the service must identify an available html or jsp page which the keepalive will use to determine
http availability. For this reason. the server should have an available html/jsp document defined.
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:
