Configuring the Local Survivable Processor
A media server can be configured either as the primary call-processing controller, or as a Local
Survivable Processor (LSP). An LSP can take over call processing if the primary call-processing
system (such as another Avaya Media Server) is unavailable for any reason (such as a network
failure or server problem). The media server can be either the primary or LSP media server; it is
set up to operate as a primary or standby LSP server during the configuration process using the
Media Server Web Interface. The license file determines the mode that the media server runs in
and the Configure Server Web page provides supplementary instruction.
If the media server loses contact with its G700 Media Gateway, the media gateway retains its
last status until the Link Loss Delay Timer (LLDT) expires. (The default for the LLDT is 5
seconds, but this interval is administrable using the
the IP-Options System Parameters
boards and deletes all call processing information. However, if the G700 loses contact with the
media server, the media gateway first tries to reconnect for a period of one minute. If this fails,
then the G700 then tries to connect with another media server in its controller list. If the primary
server was a LSP, it will start looking at the top of its MGC list in order to get back to the primary
server. Otherwise, it starts down the list of alternative servers. When a functional media server
is located, the media gateway informs the server of its current call state, and the server
maintains those connections until the users hang up.
