Service Areas are
groupings within a Domain that are used to structure and manage the required IP
telephony and messaging services across geographic, organizational, or
technological boundaries. The Service Area typically acts as a service offering
location and provides a template mechanism that determines provisioning
attribute values used during order processing.
The Service Area
determines the mappings from the business view of the service to the technology
delivering those services.
A Service Area also
handles Cisco Unified CM partitioning and class of service by directing which
location, device pool and route partition assignments to use for any user
provisioned into that Service Area.
For example, on a
Service Area associated to a Cisco Unified Communications Manager, the Service
Area defines the device pool, route partition, location, and external phone
number mask that the products will use within Cisco Unified Communications
Manager.
In this case, when you
configure a Service Area, you have a list of route partitions that can be
assigned to it based on the selected Call Processor for the Service Area. If
the Service Area does not have any associated route partition, then the
directory numbers and lines are created in the default route partition in Cisco
Unified Communications Manager. Service areas also determine the key voicemail
settings and call forwarding behaviors.
Ensure
Synchronization is completed for the Cisco Unified CM while creating the
Service Area. You can map the call processor objects (such as Route Partition,
Device Pool, and Location) to the Service Area only after the synchronization.
For
Cisco
Unity Connection Unified Message Processors, if you assign a Unified Message
Processor to a Service Area, the Subscriber Template (with or without the TTS
feature) and Subscriber CoS (with or without the TTS feature) can be
configured. These templates can be used for voicemail provisioning of users in
the Service Area.
 Note |
For
Service Areas with Call Processors based on Cisco Unified Communications
Manager Express, only device pools are available for selection. Route
partitions are not available.
