1.1 Media Server Overview
1.1.1 Introduction to Media Server
The H3C XE 200/2000 IP PBX (hereafter referred to as XE IP PBX) integrates the
functions of a location server (LS), a process server (PS), and a media server (MS), so
the XE IP PBX can serve as an LS, a PS, and/or an MS. An LS is used to record
information, provide information query, and control services. A PS is used for
processing gateway registration and call control, whereas the MS is in charge of
media services and media processing.
Specific functions of an MS include:
z
Media services, including media resource management and media negotiation.
z
Media processing, including multimedia voice playing and implements media
relaying.
Before enabling a voice service with voice prompt function, you must enable the MS.

Figure 1-1 Architecture of the XE IP PBX
As shown in the figure above, the MS and the PS are located at the same level. The
MS is managed by the LS. The MS communicates with the LS through the CAI
signaling and exchanges media information with the gateway over RTP/RTCP for
multimedia playing and media relaying.
