Configuring the Local Survivable Processor
(For S8300 or S8700 Series Media Servers) An S8300 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 S8300, or an
S8700 Series Media Server) is unavailable for any reason (such as a network failure or server
problem). The S8300 Media Servers can be either the primary or LSP media servers; they are
set up to operate as a primary or standby LSP server during the configuration process using the
S8300 Media Server Web Interface. The license file determines the mode that the S8300 Media
Server runs in and the Configure Server web page provides supplementary instruction.
(For S8300 or S8700 Series Media Servers) If the S8300 Media Server loses contact with its
G700 Media Gateway, it will take the media gateway out of service after a time-out period.
However, if the G700 loses contact with the S8300 Media Server, the media gateway first tries
to reestablish contact. If it fails after a time-out period, then the G700 tries to connect with
another media server in its controller list. When a functional media server is located, the G700
reboots.
(For S8300 or S8700 Series Media Servers) If the primary call-processing server goes offline
and an LSP is available as a standby unit, it will assume call processing as follows:
IP phones and media gateways that were previously using the primary media server will
●
try to register with the standby media server for call processing, provided that they have
been administered to do so in the controller list (use the set mgc list command).
