Dual Phone System Integration

Cisco Unity can be integrated with one each of the following phone systems at the same time:

•A traditional, circuit-switched phone system. Any traditional phone system that Cisco Unity integrates with can be used in a dual phone system integration.

•Cisco CallManager.

All extensions for subscribers and call handlers must be unique regardless of which phone system a subscriber (or call handler) uses. To transfer calls from one phone system to the other, Cisco Unity must dial the same access codes that a subscriber dials when calling someone on the other phone system.

Dual Phone System Integration Overview

Before performing the following integration steps, confirm that the Cisco Unity server is ready for the integration by completing the appropriate tasks in the Cisco Unity Installation Guide.

Integration Steps When No Phone Systems Are Installed

Requirements

The dual phone system integration supports configurations of the following components:

•A Cisco Unity system key with the integration type set to "Multiple integrations" and with the appropriate number of voice messaging ports enabled.

•The Cisco Unity server set up and Cisco Unity 3.1(1) or later installed, as described in the Cisco Unity Installation Guide.

•A traditional phone system installed and integrated with Cisco Unity. For details, see the instructions earlier in this integration guide. The traditional phone system (including the voice card software used in the integration) must be installed and integrated with Cisco Unity before Cisco CallManager is integrated.

•Cisco CallManager, version 3.2(1) or later, and the AV-Cisco service provider (TSP) installed and configured. For information about integrating Cisco Unity with Cisco CallManager and the AV-Cisco service provider, see the Cisco CallManager Integration Guide, located on Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/index.htm.

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 traditional phone system on the System > Switch > Switch page. For details, see the "To specify switch settings for the traditional phone system" section.

Caution Specify settings for the traditional 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" section.

3. On the Ports page, assign port ranges to the traditional phone system first, then to CallManager, and adjust settings for the ports assigned to each phone system. For details, see the "To modify voice port settings" section.

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" section.

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" section.

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 AV-Cisco service provider. Do not reinstall the AV-Cisco service provider 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.

To specify switch settings for the traditional phone system

Step 1 Go to System > Switch > Switch. The settings for the traditional 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 traditional phone system.

The access code is the same number that subscribers on the traditional phone system dial to reach someone on the Cisco CallManager system.

Step 3 Adjust other settings as appropriate. For more information about the other settings on the Switch page, see the online Help in the Cisco Unity Administrator.

Step 4 Click the Save icon, then click OK in the Warning dialog box.

To specify switch settings for Cisco CallManager

Step 1 Go to System > Switch > IP Switch.

Step 2 In the Set Active Switch Type section, enter values as shown in the following table:

Table 2-1 Switch Settings 

Switch Parameter
Required Setting

Manufacturer

Cisco

Model

CallManager

Switch PBX software version

3.01 or later

Integration

TAPI


Step 3 Click Set As Active, then click OK in the Warning dialog box.

Step 4 In the Access Code field, enter the trunk access code that Cisco Unity must dial to transfer calls to the traditional phone system from Cisco CallManager.

The access code is the same number that subscribers on Cisco CallManager dial to reach someone on the traditional phone system.

Step 5 Click the Save icon, then click OK in the Warning dialog box.

To modify voice port settings

Step 1 Go to System > Ports.

Step 2 In the Port Assignments section, indicate the range of ports to be assigned to the traditional phone system. The port range for the traditional phone system begins with 1 and extends to no more than the number of ports that are on the installed voice cards. Do not assign more ports to the traditional phone system than the number of ports on the voice cards.

Caution If you assign fewer voice ports to the traditional phone system than are available on the installed voice cards, you must edit the registry for this port range to take effect. Otherwise, all available voice ports on the voice cards are used in the integration regardless of the Port Assignments settings. For information on editing the registry for the port range, see the appendix "Assigning Dialogic Ports for a Dual Phone System Integration."

Step 3 In the Port Assignments section, indicate the range of ports to be assigned to Cisco CallManager. The port range must begin with the next port after the last port for the traditional phone system. The range for Cisco CallManager must end with the port number of the last port displayed on the Ports page, or the number of licensed voice ports on the system key, whichever is lower. In other words, the number of ports available for Cisco CallManager is the difference between the number of licensed voice ports on the system key and the number of ports assigned to the traditional phone system.

Step 4 Enter an extension for each port.

Step 5 Specify other settings as appropriate. For each phone system, confirm that an appropriate number of ports are used to answer calls and to dial out for message waiting indicators (MWIs), message notifications, and Media Master recordings by phone.

Step 6 Click the Save icon.

Caution The port range for each phone system must be set as specified in Steps 2 and 3 above. If there is a port range mismatch, Cisco Unity will be unable to answer incoming calls and to dial out.

To select which phone system subscribers and call handlers use

For existing subscriber templates, subscriber accounts, and call handlers, Cisco Unity uses the traditional phone system as its default. Therefore, during the initial setup of the dual phone integration, you will modify only those pages that will be using Cisco CallManager. Note that changes made to subscriber templates do not affect existing subscriber accounts.

Step 1 In Cisco Unity Administrator, go to the appropriate page:

•Subscribers > Subscriber Template > Profile

•Subscribers > Subscribers > Profile

•Call Management > Call Handlers > Profile

Step 2 In the Switch list, select the appropriate phone system.

Step 3 Adjust other settings as appropriate. For more information, see the online Help in the Cisco Unity Administrator.

Caution If the Switch setting on the Profile page for the subscriber or call handler does not match the phone system actually used by a subscriber or call handler, Cisco Unity will not be able to transfer calls to or from the subscriber or call handler. Additionally, Cisco Unity will be unable to turn the MWIs for the subscriber on or off and will be unable to reach the extension for the subscriber when recording by phone with Media Master.

To select which phone system Cisco Unity uses for message notification

If subscribers use message notification, you can select which phone system Cisco Unity dials out on when notifying subscribers of new messages. Note that changes made to subscriber templates do not affect existing subscribers.

Step 1 In Cisco Unity Administrator, go to the appropriate page:

•Subscribers > Subscriber Template > Message Notification

•Subscribers > Message Notification.

Step 2 For each device, in the Switch list select the phone system that Cisco Unity uses to dial out when notifying subscribers of new messages. Each notification device can be associated with a specific phone system (except for text pagers).

Cisco Unity uses the phone system specified on the subscriber template's Profile page as the default.

Step 3 Adjust other settings as appropriate. For more information, see the online Help in the Cisco Unity Administrator.

Caution The selected phone system must have at least one port set to dial out for message notifications on the System > Ports page. If the selected phone system does not have any ports set for this function, notifications will fail.

Changing the Number of Installed Ports

After the dual phone system integration is set up, if you need to add or remove voice cards or uninstall voice card software, follow these steps:

1. Remove the existing AV-Cisco service provider. For details, see the "To remove the existing AV-Cisco service provider" section.

2. As appropriate, remove or add voice cards, or uninstall and reinstall the voice card software. For information about removing Dialogic voice card software, refer to the chapter about voice cards in the Cisco Unity Installation Guide.

3. Reinstall the AV-Cisco service provider after you have set up the voice cards or reinstalled the voice card software. For details, see "To reinstall the AV-Cisco service provider" section.

4. Adjust the port assignments on the System > Ports page. The voice messaging ports must appear in this order in the list of ports: first are all the ports connected to the traditional phone system, second are the ports connected to CallManager.

If you completely remove the traditional phone system, you must adjust the port assignments for Cisco CallManager on the System > Ports page, after the voice cards and voice card software used in the integration with the traditional phone system have been removed.
