284 CHAPTER 10: CONFIGURING ROUTING AND TRANSLATION SERVICES
no IP Messaging services. In this case, voicemail and MOH services
are provided to all branches by the regional server.
■When a multi-site system with branch offices is configured for local
messaging, the branch offices are configured as IP Telephony and
IP Messaging systems that include both a call processor and IP
Messaging services. In this case, voicemail and MOH services are
provided locally by each branch office.
In each of these systems, you can implement IP Messaging in a
client/server configuration. An IP Messaging server can support up to 20
IP Messaging clients. One client can be dedicated to non-voice
applications such as Web provisioning, e-mail synchronization, and
logging. The remaining clients can be dedicated to voice functions. This
type of setup improves the IP Messaging server performance.
The topics in this section describe how to configure each option.
Configuring Routes for IP Messaging on a Regional Office
This example describes how to create IP Messaging routes on a regional
office. While branch users can use IP Messaging services located on either
the branch office or its host region, you must configure IP Messaging
routes on each primary regional server for users assigned to that region
(that is, users not configured on a branch).
This example describes how to create IP Messaging routes on the primary
call processor in a region. The example uses the following simple
multi-site system in which the six servers are running IP Telephony and IP
Messaging configurations:
■R1a identifies the primary call processor in region 1.
■R1b identifies the secondary call processor in region 1.
■IPM1a identifies the primary IP Messaging server in region 1.
■IPM1b identifies the secondary IP Messaging server in region 1.
■R2a identifies the primary call processor in region 2.
■R2b identifies the secondary call processor in region 2.
■IPM2a identifies the primary IP Messaging server in region 2.
■IPM2b identifies the secondary IP Messaging server in region 2.
