Paging, and Ad-Hoc Conferencing. Media Server functions also includes
voice compression and decompression, echo cancelation and DTMF
detection and generation. These processes can take up to 30 Million
Instructions per Second (MIPS) for each active media stream in a call. It
is, therefore, necessary to limit the amount of media server channels on
each platform.
The media server is a resource used by these types of applications.
These functions effect network bandwidth use. Network bandwidth
utilization needs to be considered when engineering the bandwidth
requirements between endpoints and the IPedge server. In the IPedge
system, signaling information flows from the IPedge server to the
endpoints, and audio streams flow between the endpoints. However,
when a feature involving media processing is used, the media server
becomes an endpoint in the call, and sufficient bandwidth from the
phones to the media server is required.
As a general guideline, the number of Media Server channels should be
set to 110% of the number of trunks in the system for Music on Hold and
Ad-Hoc conferencing. If a site is going to use Group Paging, the number
of media server channels should be increased by the number of stations
in the largest paging group.
For example, an IPedge system with 120 I-CP-TRUNK licenses (trunks)
and no paging groups should set the number of Media Server channels to
132. The same system with a paging group with 10 stations should have
142 Media Server channels. Do not exceed the system maximum.
Enter the number Media Server channel licenses.
1. Select Application > Media Server.
2. Do not change the SysChannelBegin parameter, the default value is
49.
3. The default value of the SysChannelTotal parameter is -1. Do not
change this value unless directed by Toshiba Engineering.
The Media Server channels must be allocated to:
• Media Server Conference channels are used for:
• Up to eight party ad-hoc conferences (Not meet-me
Conference)
• ACD monitor, Privacy override, Executive Busy override, and
other barge-in features use this function.
• Media Server Generic channels are used for:
• Music on Hold
• Back Ground Music
• Group Paging (over IPT, not overhead paging)
• Ring Back Tone (RBT) and Busy Tone (BT) is provided by the
Media Server for IPedge NET calls after the called party
