Dual Phone System Integration
Changing Cisco Unity Administrator Settings
• A circuit-switched phone system installed and integrated with Cisco Unity. For details, see the
instructions earlier in this integration guide. The circuit-switched phone system (including the voice
card software used in the integration) must be installed and integrated with Cisco Unity before
Cisco CallManager is integrated.
• A supported version of Cisco CallManager and the Cisco Unity-CM service provider (TSP) installed
and configured. For information about integrating Cisco Unity with Cisco CallManager and the
Cisco Unity-CM service provider, see the applicable Cisco CallManager integration guide, located
at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_configuration_guides_list.html.
Changing Cisco Unity Administrator Settings
After Cisco Unity is installed and the phone systems have been separately integrated, you need to adjust
settings on pages in the Cisco Unity Administrator so that Cisco Unity can work with both phone
systems.
Follow these steps to set up the dual phone system integration.
1. Specify settings for the circuit-switched phone system on the System > Switch > Switch page. For
details, see the “To Specify Switch Settings for the Circuit-Switched Phone System” procedure on
page 27.
Caution Specify settings for the circuit-switched phone system before specifying settings for
Cisco CallManager. You must proceed in this order, or the integration may not work.
2. Specify settings for Cisco CallManager on the IP Switch page. For details, see the “To specify
switch settings for Cisco CallManager” procedure on page 28.
3. On the Ports page, assign port ranges to the circuit-switched phone system first, then to
Cisco CallManager, and adjust settings for the ports assigned to each phone system. For details, see
the “To Modify Voice Port Settings” procedure on page 28.
4. Select the phone system that subscribers and call handlers use. For details, see the “To Select Which
Phone System Subscribers and Call Handlers Use” procedure on page 29.
5. Select the phone system that Cisco Unity uses when dialing out to send message notifications. For
details, see the “To Select Which Phone System Cisco Unity Uses for Message Notification”
procedure on page 29.
Caution If you need to add or remove voice cards or uninstall the voice card software after the dual
phone system integration is set up, you must also reinstall the TSP (Cisco Unity-CM service
provider). Do not reinstall the TSP until after you have set up the voice cards or reinstalled
the voice card software. For more information, see the “Changing the Number of Installed
Ports” section on page 30.
To Specify Switch Settings for the Circuit-Switched Phone System
Step 1 In the Cisco Unity Administrator, go to the System > Switch > Switch page. The settings for the
circuit-switched phone system selected during the Cisco Unity Setup program appear.
Step 2 In the Access Code field, enter the trunk access code that Cisco Unity must dial to transfer calls to
Cisco CallManager from the circuit-switched phone system.
