The media servers are standard http servers. CSS supports varying methods of keepalives used to 
determine the availability of an individual service.

For media servers, the http keepalive method is recommended. This will ensure that 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 page which the keepalive will use to determine http availability. For this 
reason, in addition to the CVP prompt audio files, the server should have an available html document 
defined. The example assumes an “index.html” document is available on the media servers. The http 
keepalive method will continuously check for the availability of this document as a means to determine 
that the server is alive and capable of serving documents. 

It is essential that all media servers included in a Media Server Content rule contain all of the CVP audio 
prompt files intended for use by that content rule to ensure that no matter which server CSS directs the 
request to, the prompt file will be available.

Use these CSS commands to setup the http keepalives while configuring each media server service:

Because these services are directly involved in processing voice calls, the shortest possible failover and 
re-activation times are desired. As such, set the following keepalive parameters:

Define a group for the participating media servers if your configuration requires source groups (see the 
discussion of Groups in the 

 section above for details.)

Activate services, group and rules:

Activate each service and group of media-servers.
