9 – 28 ShoreTel, Inc.
placed from any extension, each switch is able to route the call to the correct ShoreGear
switch based on its internal routing database.
When Distributed Routing Service is enabled, ShoreGear switches only exchange
routing information with other switches at the same site rather than exchanging
routing information with every other switch in a multi-site system. Although each
ShoreGear switch only maintains routing information within its site, each ShoreWare
server also includes an instance of the Distributed Routing Service which maintains
system-wide routing information. When calls are initiated, ShoreGear switches contact
the Distributed Routing Service in order to find the ShoreGear switch or switches
needed to complete the call.
In a system with more than one ShoreWare server, the ShoreGear switches may contact
an alternate instance of the routing service if the primary instance is not reachable.
ShoreWare servers have a hierarchical relationship and switches first try to contact the
nearest instance of the Distributed Routing Service in the hierarchy. If that instance of
DRS is not reachable, the instance of DRS at the parent server in the hierarchy will be
contacted as a fallback. If both instances of DRS are not reachable the switch will make
a best effort to route the call based on its internal routing tables built from
communicating with peer ShoreGear switches at the same site.
