CSS Configuration for Media Servers

Media Servers are standard web servers that are responsible for serving Unified CVP prompt
files to the voice gateway.

Note: The following sample configuration applies only to Comprehensive configuration (Type
7), when the Voice Gateway is making the request for the media file. Do not use media servers
in Type 5 configurations where the Unified CVP H.323 Service is requesting media files. The
Unified CVP H.323 Service does not support redirect and all media requests would be channeled
through the content server. This would degrade performance considerably.
