Chapter 1 Product Overview
Integrating Cisco Unified Attendant Console Advanced with Cisco Unified Communications Manager
• The Cisco Unified Communications Manager that will use it (see Step 12, in the Cisco Unified
Attendant Console Advanced Server Installation Procedure). In resilient installations the Publisher
and Subscriber servers both need this information.
• The Primary and Backup CTI Manager that will use it (see Step 14, in the Cisco Unified Attendant
Console Advanced Server Installation Procedure).
CTI Manager is a feature service that runs on one or more Cisco Unified Communications Manager
subscribers operating in primary/secondary mode to authenticate and authorize Cisco Unified
Attendant Console Advanced. A CTI Manager node is a Cisco Unified Communications Manager
subscriber that runs only the CTI Manager service.
The Cisco Unified Attendant Console Advanced server installer uses AXL to verify that the specified
CTI manager(s) and Cisco Unified Communications Manager versions match, which is essential for
successful implementation. After Cisco Unified Attendant Console Advanced is installed, the CTI
Manager nodes no longer require the AXL service; so you can disable it. However, if the main Cisco
Unified Communications Manager node and the CTI Manager nodes are hosted on the same servers, you
need to retain the AXL service on them.
AXL Usage After Installation
Part of the Cisco Unified Attendant Console Advanced BLF Plug-in service known as Device Resolution
Manager (DRM) uses AXL to communicate with Cisco Unified Communications Manager. The AXL
communications enable DRM to resolve the BLFs of operator and system devices, and to synchronize
system devices within the Cisco Unified Communications Manager database. System device
synchronization is described further in AXL API, page 1-9.
Non-resilient Installation Scenarios
This section describes AXL usage in example non-resilient Cisco Unified Attendant Console Advanced
server installations.
Scenario 1
This scenario uses the following node IP addresses:
• Cisco Unified Communications Manager = 172.29.252.111
• Primary CTI Manager = 172.29.252.111
• Backup CTI Manager = 172.29.252.112
DRM uses only the Cisco Unified Communications Manager at 172.29.252.111. Consequently, the AXL
service can be disabled on 172.29.252.112 after installing Cisco Unified Attendant Console Advanced.
Scenario 2
This scenario uses the following node IP addresses:
• Cisco Unified Communications Manager = 172.29.252.111
• Primary CTI Manager = 172.29.252.112
• Backup CTI Manager = 172.29.252.113
DRM uses only the Cisco Unified Communications Manager at 172.29.252.111. Consequently, the AXL
service can be disabled on 172.29.252.112 and 172.29.252.113 after installing Cisco Unified Attendant
Console Advanced.
