Overview
Cisco Unified
Communications Manager devices provide the core call processing capabilities
for HCS, and are a critical part of the Cisco Unified Communications Domain
Manager provisioning workflows.
Cisco Unified
Communications Manager
devices must be configured before dial plan, user, subscriber, line, and phone
configuration can be completed.
Cisco Unified
Communications Manager
devices can be dedicated to a specific customer, or they can be shared between
multiple customers.
Cisco Unified
Communications Manager
devices must then be assigned to one or more Network Device Lists (NDLs), and
the NDL is then assigned to one or more sites. The NDL is used to select which
Cisco Unified
Communications Manager
is used for configuration based on the site selected in the hierarchy context.
Shared versus Dedicated
To share the
Cisco Unified
Communications Manager
across multiple customers, add the
Cisco Unified
Communications Manager
at the Provider or Reseller level. To dedicate the
Cisco Unified
Communications Manager
to a single customer, add the
Cisco Unified
Communications Manager
at the Customer level.
When setting up
Cisco Unified
Communications Manager
as a dedicated instance, you can opt to set up
Cisco Unified
Communications Manager
after you create the customer.
Servers within a Cisco
Unified Communications Manager Cluster
Within a
Cisco Unified
Communications Manager
cluster, you can configure the following nodes:
-
Cisco Unified
Communications Manager
Publisher
-
Cisco Unified
Communications Manager
Subscriber
-
IM and Presence
Service Publisher
-
IM and Presence
Service Subscriber
You must configure a
Cisco Unified
Communications Manager
Publisher node before configuring any other type node.
You must configure
an IM and Presence Service Publisher node before configuring an IM and Presence
Service Subscriber node.
Synchronization with
Cisco Unified
Communications Domain Manager 10.6(1)
Configuring a
Cisco Unified
Communications Manager
device on
Cisco Unified
Communications Domain Manager 10.6(1)
creates a scheduled data sync to import model data from the device into
Cisco Unified
Communications Domain Manager 10.6(1).
The scheduled data sync ensures that the
Cisco Unified
Communications Domain Manager 10.6(1)
cache maintains the most current view of the configured device. Any changes to
the configuration occurring on the device, including additions, deletions, or
modifications, will be reflected in
Cisco Unified
Communications Domain Manager 10.6(1)
after the next data sync.
The data sync
occurs once immediately upon creation. The recurring sync is scheduled to occur
every 14 days, but is disabled by default. You can enable the sync and modify
the schedule from
. When determining the
appropriate schedule setting, the frequency of the sync must be weighed against
the additional processing and network activity associated with the data sync.
You can also manually run the data sync at any time from
, or from
.
When you set up an IM and
Presence Service server,
Cisco Unified
Communications Domain Manager 10.6(1)
does not communicate directly with the IM and Presence Service server, but the
information provided is pushed to HCM-F and Service Assurance for monitoring
purposes.
The performance of a
data sync can be improved by controlling the types of data that are synced. See
Controlling a Data Sync with a Model Type List
for more information.
