Multiple Phone System Integration Guide for Cisco Unity 5.0
Revised August 16, 2007
This document applies to Cisco Unity 5.0. It provides instructions for integrating multiple phone systems with Cisco Unity (limited only by the number of licensed voice messaging ports and the phone systems type), deleting one of the phone systems that is integrated with Cisco Unity, and replacing one phone system with another phone system in a Cisco Unity integration.
Caution 
A trunk must be set up between the integrated phone systems so that Cisco Unity can transfer calls from one integrated phone system to another integrated phone system. Otherwise, Cisco Unity cannot transfer calls between integrated phone systems. For details on setting up a trunk between phone systems, see the phone system documentation.
Integration Tasks
Before doing the following tasks to integrate Cisco Unity with multiple phone systems, confirm that the Cisco Unity server is ready for the integration by completing the applicable tasks in the applicable Cisco Unity installation guide.
The following task lists describe the process for creating, deleting, and replacing the integrations.
Task List to Create Multiple Phone System Integrations
Use the following task list to integrate multiple phone systems with Cisco Unity. If you are installing a new Cisco Unity server by using the applicable Cisco Unity installation guide, you may have already completed some of the following tasks.
1. Review the system and equipment requirements to confirm that all phone system and Cisco Unity server requirements have been met. See the "Requirements" section.
2. Confirm that the combination of phone systems is supported in a multiple phone system integration with Cisco Unity. See the "Combination Limitations for Multiple Phone System Integrations" section.
3. Create the integration. See the "Creating Multiple Phone System Integrations" section.
Note Multiple Cisco Unified Communications Manager clusters can be integrated by creating a new integration for each Cisco Unified Communications Manager cluster in UTIM or by adding new clusters to an existing Cisco Unified Communications Manager integration in UTIM. For instructions, see the "Creating an Integration with a Second Cluster of Cisco Unified Communications Manager" section in the applicable Cisco Unified Communications Manager integration guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.
4. Repeat Task 1. through Task 3. for each remaining phone system.
Task List to Delete an Existing Phone System Integration
Use the following task list to delete one of the phone systems that is integrated with Cisco Unity (for example, to change from two phone system integrations to a single phone system integration).
1. Start the Cisco Unity Telephony Integration Manager (UTIM). See the "Deleting an Existing Phone System Integration" section.
2. Delete the existing integration. See the "Deleting an Existing Phone System Integration" section.
3. Reassign the subscribers and call handlers who had been homed on the deleted phone system integration to a remaining phone system integration. See the "Deleting an Existing Phone System Integration" section.
Task List to Replace an Existing Phone System Integration with a New Phone System Integration
Use the following task list to replace an existing phone system with a new phone system and to reassign the subscribers and call handlers to the new phone system.
1. Review the system and equipment requirements to confirm that all phone system and Cisco Unity server requirements have been met. See the "Requirements" section.
2. Confirm that the combination of phone systems is supported in a multiple phone system integration with Cisco Unity. See the "Combination Limitations for Multiple Phone System Integrations" section.
3. Create the integration for the new phone system. See the "Replacing an Existing Phone System with a New Phone System" section.
4. Delete the old phone system. See the "Replacing an Existing Phone System with a New Phone System" section.
5. Reassign the subscribers and call handlers who had been homed on the deleted phone system to the new phone system. See the "Replacing an Existing Phone System with a New Phone System" section.
Requirements
Cisco Unity has the following requirements for multiple phone system integrations:
•All phone system and Cisco Unity server requirements have been met. See the applicable Cisco Unity integration guides at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.
•There must be an adequate number of voice messaging ports on the Cisco Unity server to connect to the phone systems. This number must not exceed the number of ports that are enabled by the Cisco Unity license files.
•For a single Cisco Unity server (or a failover pair), all extensions must be unique. The dial plans for the phone systems must not overlap.
If overlapping dial plans cannot be avoided, you must install a Cisco Unity server for each phone system, digitally network the servers, and set up dialing domains to accommodate the overlapping dial plans. See the applicable Networking Guide for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guides_list.html.
Combination Limitations for Multiple Phone System Integrations
Cisco Unity 5.0 supports multiple simultaneous phone system integrations in any combination with the following limitations:
•The number of simultaneous phone system integrations is limited by the number of licensed voice messaging ports on the Cisco Unity server.
•Only one integration with a circuit-switched phone system through voice cards is supported on the Cisco Unity server.
•A QSIG/DPNSS phone system integration must be the only phone system integration on the Cisco Unity server. QSIG/DPNSS phone systems integrations cannot be combined with any other phone system integrations.
For example, Cisco Unity can be integrated with the following phone systems at one time (a total of 22 phone system integrations):
•Seven circuit-switched phone systems through PIMG/TIMG units
•Seven Cisco Unified Communications Manager phone systems through Skinny Call Control Protocol (SCCP)
•One circuit-switched phone system through voice cards
•Seven Cisco Unified Communications Manager phone systems through SIP trunk
Creating Multiple Phone System Integrations
After ensuring that the Cisco Unity server and the phone systems are ready for the integration, do the following procedure.
To Create Multiple Phone System Integrations
Step 1 Integrate one phone system with Cisco Unity. See the applicable Cisco Unity integration guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.
You can integrate the phone systems with Cisco Unity in any order.
Step 2 Repeat Step 1 for the remaining phone systems.
Step 3 Revise the applicable subscriber templates and call handler templates so that new subscribers and call handlers will be automatically assigned to the phone system that you want. For details, see the applicable System Administration Guide for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_maintenance_guides_list.html.
Deleting an Existing Phone System Integration
If you want to delete an existing phone system integration (for example, you have replaced the phone system with which Cisco Unity originally integrated), do the following procedure.
To Delete an Existing Phone System Integration
Step 1 On the Cisco Unity server, on the Windows Start menu, click Programs > Cisco Unity > Manage Integrations. The UTIM window appears.
Step 2 In the left pane, double-click Unity Server. The existing integrations appear.
Step 3 Click the integration that you want to delete.
Step 4 On the Integration menu, click Delete.
Step 5 Follow the on-screen instructions to assign the subscribers and call handlers of the deleted phone system integration to another phone system integration.
Step 6 At the prompt to restart the Cisco Unity services, click Yes. The Cisco Unity services restart.
Alternatively, you can restart the Cisco Unity services in UTIM on the Tools menu by clicking Restart Cisco Unity.
Step 7 Revise the applicable subscriber templates and call handler templates so that new subscribers and call handlers will be automatically assigned to another phone system. For details, see the applicable System Administration Guide for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_maintenance_guides_list.html.
Step 8 If the integration that you deleted used voice cards, remove the voice cards from the Cisco Unity server.
Replacing an Existing Phone System with a New Phone System
If you want to replace an existing phone system with a new phone system, you can use a temporary multiple phone system integration to automatically reassign to the new phone system all of the subscribers and call handlers who are currently assigned to the existing phone system. This process involves the following tasks:
1. Create a second integration for the new phone system.
2. Delete the integration for the existing phone system.
3. UTIM reassigns to the new phone system all of the subscribers and call handlers who are currently assigned to the existing phone system.
Do the following procedure.
To Replace an Existing Phone System with a New Phone System, Then Reassign Subscribers and Call Handlers
Step 1 Integrate the new phone system with Cisco Unity. See the applicable Cisco Unity integration guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.
Step 2 If the UTIM window is not open, on the Windows Start menu, click Programs > Cisco Unity > Manage Integrations. The UTIM window appears.
Step 3 In the left pane, double-click Unity Server. The existing integrations appear.
Step 4 Click the existing integration (the integration that you want to delete).
