Chapter 1  Media Server

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:

l           Media services, including media resource management and media negotiation.

l           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.

The MS is connected to the LS in two modes:

l           Centralized networking: the MS and the LS are deployed on the same XE IP PBX, where the LS mode of the MS is set to “local”.

l           Distributed networking: the MS and the LS are deployed on two different XE IP PBXs, where the LS mode of the MS is set to “remote”.

1.2.2  Uploading Media Resource Files

Typically, FTP or TFTP is used to upload media resource files to the XE IP PBX. For how to upload files through TFTP, refer to section 5.4 “TFTP Configuration” in the “System Management Operation” module of this manual. The following sections describe how to upload media files in batch mode through FTP.

I. Configuring the FTP user information on the XE IP PBX

Table 1-2 Configure the FTP user information

II. Configuring the FTP server information on the XE IP PBX

Table 1-3 Configure the FTP server information

III. Using the Web explorer on a PC to upload media resource files to the XE IP PBX

1)         Select [Start/Programs/Internet Explorer] to launch the Web browser.

Figure 1-2 Launch the Web browser

2)         Input ftp://username:[email protected] in the address bar, and then press Enter to log in to the XE IP PBX. Input your username in the place of “username”, input your password in the place of “password”, and input the IP address of the XE IP PBX in the place of “xxx.xxx.xxx.xxx”. As shown in the following figure, ftp://xeuser:[email protected] indicates that the user “xeuser” is logging in to the XE IP PBX: the password is “loginkey”, and the IP address of the XE IP PBX is 192.168.1.10.
