5. Administration
The LSP must be administered to know where the primary call controller is so
that a registration and heartbeat will occur between the LSP and the primary call
controller. This administration on the LSP is done during the configuration stage through
the configure server web page.
Starting with Avaya MultiVantage Software Release 1.3 (Planned 2003 release),
the primary gatekeeper will also be administered to know about each of the LSPs via
programming on the System Administration Terminal (SAT). This added feature will
provide security against a registration from a false LSP that would then impair the
remaining LSPs. Additionally, as LSPs become available for translation transfers, the
primary gatekeeper’s SAT will show this information.
6. Translations
The primary gatekeeper sends a complete copy of the Media Server translations to
the LSP. Once the LSP has contacted the primary gatekeeper, the primary gatekeeper
saves the location of the LSP and records that it is ready for translations to be transferred.
Then, when a save translations command is run (either manually or through the scheduled
maintenance), a file transfer occurs to each of the LSPs that are in the primary
gatekeeper’s list. Once the transfer has completed to the LSP, a reset of Avaya
MultiVantage Software automatically occurs on each LSP in order for the LSP to read in
all changes made to translations.
Each LSP is running MultiVantage Software all the time, but it is only when the
G700 registers that the LSP becomes active and begins processing calls. When the LSP
is active, translations may still be transferred from the primary gatekeeper, but the LSP
will recognize that it is active and not read in the new translations until it is no longer
performing call processing.
The translation transfer will only happen from the primary call controller to the
LSPs. Because there may be multiple LSPs in a system, translations are not transferred
back to the primary call controller to maintain the integrity of the translations. The LSP
allows administration changes, allowing for a flexible emergency system, but those
changes cannot be saved on the LSP.
7. Preparing for transition to an LSP
The LSP will serve any registering endpoints in the event of a network failure or
when the primary call controller is unable to provide service. The transition sequence is
driven by the endpoints; in order for a transition to happen properly in either case, the IP
telephones and Avaya G700 Gateways must be administered to know where the LSP
resides.
