Connecting to IP Media Server

Descriptions

IP media server is the name given to the computing component that processes the audio streams associated with telephone calls or connections. Multi-party call and conference services are particular examples of how IP media servers can be used, as a special 'engine' is needed to mix audio streams together so that conference participants can hear all of the other participants.
