IP Media Server for Processing Voice and Video

An IP media server is the endpoint that terminates an IP connection in a network, and it is deployed differently in service provider 
and enterprise environments. Configurations for IP media servers that can be developed with PowerMedia HMP 4.1 include video 
transcoding gateway, video transcoding media server, video portal, network announcement, IVR, voice mail, and conferencing 
server.

The following sections discuss example deployment environments.

Figure  1  illustrates  how  an  IP  media  server  based  on  PowerMedia  HMP  4.1  can  be  deployed  in  a  typical  service  provider 
environment to deliver messaging, IVR, announcements, voice mail, speech, or conferencing applications. PowerMedia HMP 4.1 
also enables video versions of many of these applications.

An IP-PSTN gateway terminates PSTN connections, and a softswitch manages all aspects of call establishment and teardown over 
IP. Once the call is established, an RTP connection is created between the IP media server and an endpoint. The softswitch tells 
the media server, IP endpoints, and IP-PSTN gateway when to establish or drop connections.
