G700 Media Gateway administration
Issue 5 October 2002 553555-233-506
(For S8300 and S8700 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).
■ The standby media server (LSP) will go into license error mode, then start
to provide call processing. It cannot preserve any calls set up by the
primary media server. IP phone connections can stay up until the call is
completed if they are shuffled, but no features are supported on the call.
NOTE:
The license error mode will run for up to 10 days and if the problem
is not resolved, then it goes into no license mode and call processing
halts.
■ When the primary media server is available again, it will begin handling
call processing. However, those endpoints that are now using the standby
media server will continue to do so until the standby unit is rebooted.
■ If the standby S8300 Media Server is rebooted, all devices will return to
using the primary media server for call-processing service. Any calls in
progress on the LSP will be dropped when the reboot occurs (the change
back to the primary media server is not call preserving).
■ With LSP functionality, there is full functionality and feature support.
Using Device Manager to administer G700
Media Gateway components
(For S8300 and S8700 Media Servers) Device Manager, also known as the P330
Embedded Web Manager, provides a browser-based graphical user interface
(GUI) to assist you with ongoing media gateway administration. For complete
information on using Device Manager, see the Avaya User’s Guide P330
Manager.
(For S8300 and S8700 Media Servers) Device Manager allows you to:
■ View the status of different devices on the network.
■ Configure or modify devices including Virtual LAN (VLAN) groupings,
port mirroring, and Simple Network Management Protocol (SNMP) traps.
