Route Plan
Configuration for
Multi-site Systems
In a multi-site system, VCX services run on servers at multiple locations. A
multi-site system can include:
■A regional site with one or more associated branch offices.
■Multiple regional sites with each region supporting one or more
associated branch offices.
■Multiple regional sites with no associated branch offices.
You need to create end points to identify the call processors at all regional
and branch offices, define routes containing the appropriate end points
for each region and branch, and create route plans at each site that
associate a route with a dial string pattern. This enables the call processor
at each site to route a dialed number to the correct destination (end
point).
For example, in a VCX multi-site system, a regional office must have
routes created to:
■Itself
■The other call processor in the redundant pair of VCX servers
■Gateways, so that calls can be placed throughout the PSTN
■Each regional office this call processor wants to communicate with
■Each branch office hosted by the regional office
■The IP Messaging server (for Music On Hold and voicemail services) it
is associated with
A regional office acts as a redirect call processor for any supported branch
offices. Therefore, you need only create a route on each branch office
that points to its host regional office (not to other branches or other
regions; the branch’s regional host will redirect all calls to other
destinations). Each branch also needs a route that points to the IP
Messaging server if a local messaging configuration is used (in other
words, the branch office is an IP Telephony and IP Messaging
configuration that includes a call processor server and an IP Messaging
server).
Beginning with VCX version 7.0, you can set up IP Messaging in a
client/server configuration. An IP Messaging server can support up to 20
IP Messaging clients. You must define a route on the regional call
processor that point to the IP Messaging servers (primary and secondary)
and to each client.
