This document provides instructions for integrating a QSIG-enabled phone system with Cisco Unity Connection through a Cisco ISR voice gateway.

Integration Tasks

Before doing the following tasks to integrate Cisco Unity Connection with a QSIG-enabled phone system through a Cisco ISR voice gateway, confirm that Cisco Unity Connection is ready for the integration by completing the applicable tasks in the Installation Guide for Cisco Unity Connection.

The following task list describes the process for creating the integration.

Task List to Create the Integration

Use the following task list to integrate Cisco Unity Connection with a QSIG-enabled phone system through a Cisco ISR voice gateway. If you are installing Cisco Unity Connection by using the Installation Guide for Cisco Unity Connection, 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 Connection server requirements have been met. See the "Requirements" section.

2. Plan how the voice messaging ports will be used by Cisco Unity Connection. See the "Planning How the Voice Messaging Ports Will Be Used by Cisco Unity Connection" section.

3. Program the QSIG-enabled phone system. See the "Programming the QSIG-Enabled Phone System" section.

4. Configure the Cisco ISR voice gateway. See the "Configuring the Cisco ISR Voice Gateway" section.

5. Create the integration. See the "Creating a New Integration with the QSIG-enabled Phone System" section.

6. Test the integration. See the "Testing the Integration" section.

7. If this integration is a second or subsequent integration, add the applicable new user templates for the new phone system. See the "(Multiple Integrations Only) Adding New User Templates" section.

Requirements

The QSIG-enabled integration supports configurations of the following components:

Phone System

A QSIG-enabled phone system.

The phone system is ready for the integration.

Cisco ISR Voice Gateway

Cisco IOS version 12.4(11)T or later.

The QSIG-enabled phone system connected to the Cisco ISR voice gateway.

Cisco Unity Connection Server

Cisco Unity Connection installed and ready for the integration, as described in the Installation Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/prod_installation_guides_list.html.

A license that enables the applicable number of voice messaging ports.

Integration Description

This integration uses a Cisco ISR voice gateway and a LAN or WAN to connect Cisco Unity Connection and a QSIG-enabled phone system. The Cisco ISR voice gateway converts the QSIG communications to SIP. Figure 1 shows the required connections.

Figure 1 Connections Between the Phone System and Cisco Unity Connection

Call Information

The QSIG-enabled phone system integration sends the following information with forwarded calls:

The extension of the called party

The extension of the calling party (for internal calls) or the phone number of the calling party (if it is an external call and the system uses caller ID)

The reason for the forward (the extension is busy, does not answer, or is set to forward all calls)

Cisco Unity Connection uses this information to answer the call appropriately. For example, a call forwarded to Cisco Unity Connection is answered with the personal greeting of the user. If the phone system routes the call to Cisco Unity Connection without this information, Cisco Unity Connection answers with the opening greeting.

Integration Functionality

The QSIG-enabled phone system integration with Cisco Unity Connection provides the following features:

Call forward to personal greeting

Call forward to busy greeting

Caller ID

Easy message access (a user can retrieve messages without entering an ID because Cisco Unity Connection identifies the user based on the extension from which the call originated; a password may be required)

Identified user messaging (Cisco Unity Connection identifies the user who leaves a message during a forwarded internal call, based on the extension from which the call originated)

Message waiting indication (MWI)

Integrations with Multiple Phone Systems

When Cisco Unity Connection is installed as Cisco Unified Communications Manager Business Edition (CMBE)—on the same server with Cisco Unified Communications Manager—Cisco Unity Connection cannot be integrated with multiple phone systems at one time.

When Cisco Unity Connection is not installed as Cisco Unified CMBE, Cisco Unity Connection can be integrated with multiple phone systems at one time. For information on and instructions for integrating Cisco Unity Connection with multiple phone systems, refer to the Multiple Phone System Integration Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/products_installation_and_configuration_guides_list.html.

Planning How the Voice Messaging Ports Will Be Used by Cisco Unity Connection

Before programming the phone system, you need to plan how the voice messaging ports will be used by Cisco Unity Connection. The following considerations will affect the programming for the phone system (for example, setting up the hunt group or call forwarding for the voice messaging ports):

The number of voice messaging ports installed.

The number of voice messaging ports that will answer calls.

The number of voice messaging ports that will only dial out, for example, to send message notification, to set message waiting indicators (MWIs), and to make telephone record and playback (TRAP) connections.


Note The Cisco ISR voice gateway will perform transfers by hairpinning two independent calls across two b-channels on the QSIG trunk. Hairpinned calls will use more QSIG channels in comparison to the number of Cisco Unity Connection voice messaging ports that are available to answer calls.

Release (blind) transfers that are forwarded back to Cisco Unity Connection will use three b-channels for the remainder of the call. However, supervised transfers pull back the consulting call when the target is unavailable so that only one b-channel is used for the remainder of the call.


The following table describes the voice messaging port settings in Cisco Unity Connection that can be set on Telephony Integrations > Port of Cisco Unity Connection Administration.

Table 1 Settings for the Voice Messaging Ports 

Field
Considerations

Enabled

Check this check box to enable the port. The port is enabled during normal operation.

Uncheck this check box to disable the port. When the port is disabled, calls to the port get a ringing tone but are not answered. Typically, the port is disabled only by the installer during testing.

Answer Calls

Check this check box to designate the port for answering calls. These calls can be incoming calls from unidentified callers or from users.


Caution All voice messaging ports connecting to the Cisco ISR voice gateway must have the Answer Calls box checked. Otherwise, calls to Connection may not be answered.

Perform Message Notification

Check this check box to designate the port for notifying users of messages. Assign Perform Message Notification to the least busy ports.

Send MWI Requests

Check this check box to designate the port for turning MWIs on and off. Assign Send MWI Requests to the least busy ports.

Allow TRAP Connections

Check this check box so that users can use the port for recording and playback through the phone in Cisco Unity Connection web applications. Assign Allow TRAP Connections to the least busy ports.


The Number of Voice Messaging Ports to Install

The number of voice messaging ports to install depends on numerous factors, including:

The number of calls Cisco Unity Connection will answer when call traffic is at its peak.

The expected length of each message that callers will record and that users will listen to.

The number of users.

The number of calls made for message notification.

The number of MWIs that will be activated when call traffic is at its peak.

The number of TRAP connections needed when call traffic is at its peak. (TRAP connections are used by Cisco Unity Connection web applications to play back and record over the phone.)

The number of calls that will use the automated attendant and call handlers when call traffic is at its peak.

It is best to install only the number of voice messaging ports that are needed so that system resources are not allocated to unused ports.

The Number of Voice Messaging Ports That Will Answer Calls

The calls that the voice messaging ports answer can be incoming calls from unidentified callers or from users. Assign all of the voice messaging ports to answer calls.

You can set voice messaging ports to both answer calls and to dial out (for example, to send message notifications).


Note The Cisco ISR voice gateway will perform transfers by hairpinning two independent calls across two b-channels on the QSIG trunk. Hairpinned calls will use more QSIG channels in comparison to the number of Cisco Unity Connection voice messaging ports that are available to answer calls. If your system uses Cisco Unity Connection auto-attendant transfers, you must provision a larger number of QSIG b-channels than the number of Cisco Unity Connection voice messaging ports that will answer calls.


The Number of Voice Messaging Ports That Will Dial Out

Ports that will only dial out can do one or more of the following:

Notify users by phone, pager, or e-mail of messages that have arrived.

Turn MWIs on and off for user extensions.

Make a TRAP connection so that users can use the phone as a recording and playback device in Cisco Unity Connection web applications.

Preparing for Programming the Phone System

Record your decisions about the voice messaging ports to guide you in programming the phone system.

Programming the QSIG-Enabled Phone System

For information on provisioning the phone system for QSIG interoperability, see the phone system documentation.

Note that you must program each extension to forward calls to the pilot number assigned to the voice messaging ports, based on one of the call transfer types shown in Table 2.

Table 2 Call Transfer Types 

Transfer Types
Usage

Release transfer
(blind transfer)

Program the phone to forward calls to the pilot number when:

The extension is busy

The call is not answered

Supervised transfer

Program the phone to forward calls to the pilot number only when the call is not answered (on the phone system, the number of rings before forwarding must be more than the number of rings to supervise the call). Confirm that call forwarding is disabled when the extension is busy.


Configuring the Cisco ISR Voice Gateway


Note If the Cisco Unity Connection SIP Port setting will not be 5060 (for example, if it is set to 5061), you must change the SIP port that the Cisco ISR voice gateway uses. You can use a command similar to the following:
dial-peer voice 1 voip
 session protocol sipv2
 session target ipv4:10.00.00.00:5061

Do not close the Cisco Unity Connection Administration window because you will use it again in a later procedure.

Step 21 Log on to the Real-Time Monitoring Tool (RTMT).

Step 22 On the Unity Connection menu, click Port Monitor. The Port Monitor tool appears in the right pane.

Step 23 In the right pane, click Start Polling. The Port Monitor will display which port is handling the calls that you will make.


To Test an External Call with Release Transfer


Step 1 From Phone 2, enter the access code necessary to get an outside line, then enter the number outside callers use to dial directly to Cisco Unity Connection.

Step 2 In the Port Monitor, note which port handles this call.

Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.

Step 4 Confirm that Phone 1 rings and that you hear a ringback tone on Phone 2. Hearing a ringback tone means that Cisco Unity Connection correctly released the call and transferred it to Phone 1.

Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call changes to "Idle." This state means that release transfer is successful.

Step 6 Confirm that, after the number of rings that the phone system is set to wait, the call is forwarded to Cisco Unity Connection and that you hear the greeting for the test user. Hearing the greeting means that the phone system forwarded the unanswered call and the call-forward information to Cisco Unity Connection, which correctly interpreted the information.

Step 7 On the Port Monitor, note which port handles this call.

Step 8 Leave a message for the test user and hang up Phone 2.

Step 9 In the Port Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.

Step 10 Confirm that the MWI on Phone 1 is activated. The activated MWI means that the phone system and Cisco Unity Connection are successfully integrated for turning on MWIs.


To Test Listening to Messages


Step 1 From Phone 1, enter the internal pilot number for Cisco Unity Connection.

Step 2 When asked for your password, enter the password for the test user. Hearing the request for your password means that the phone system sent the necessary call information to Cisco Unity Connection, which correctly interpreted the information.

Step 3 Confirm that you hear the recorded voice name for the test user (if you did not record a voice name for the test user, you will hear the extension number for Phone 1). Hearing the voice name means that Cisco Unity Connection correctly identified the user by the extension.

Step 4 Listen to the message.

Step 5 After listening to the message, delete the message.

Step 6 Confirm that the MWI on Phone 1 is deactivated. The deactivated MWI means that the phone system and Cisco Unity Connection are successfully integrated for turning off MWIs.

Step 7 Hang up Phone 1.

Step 8 On the Port Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.


To Set Up Supervised Transfer on Cisco Unity Connection


Step 1 In Cisco Unity Connection Administration, on the Edit Transfer Option page for the test user, in the Transfer Type field, click Supervise Transfer.

Step 2 In the Rings to Wait For field, enter 3.

Step 3 Click Save.

Step 4 Minimize the Cisco Unity Connection Administration window.

Do not close the Cisco Unity Connection Administration window because you will use it again in a later procedure.


To Test Supervised Transfer


Step 1 From Phone 2, enter the access code necessary to get an outside line, then enter the number outside callers use to dial directly to Cisco Unity Connection.

Step 2 On the Port Monitor, note which port handles this call.

Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.

Step 4 Confirm that Phone 1 rings and that you do not hear a ringback tone on Phone 2. Instead, you should hear the indication your phone system uses to mean that the call is on hold (for example, music).

Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call remains "Busy." This state and hearing an indication that you are on hold mean that Cisco Unity Connection is supervising the transfer.

Step 6 Confirm that, after three rings, you hear the greeting for the test user. Hearing the greeting means that Cisco Unity Connection successfully recalled the supervised-transfer call.

Step 7 During the greeting, hang up Phone 2.

Step 8 On the Port Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.

Step 9 Click Stop Polling.

Step 10 Exit RTMT.


To Delete the Test User


Step 1 In Cisco Unity Connection Administration, expand Users, then click Users.

Step 2 On the Search Users page, check the check box to the left of the test user.

Step 3 Click Delete Selected.


(Multiple Integrations Only) Adding New User Templates

When you create the first phone system integration, this phone system is automatically selected in the default user template. The users that you add after creating this phone system integration will be assigned to this phone system by default.

However, for each additional phone system integration that you create, you must add the applicable new user templates that will assign users to the new phone system. You must add the new templates before you add new users who will be assigned to the new phone system.

For details on adding new user templates, refer to the "Adding, Changing, or Deleting an Account Template" chapter in the User Moves, Adds, and Changes Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html.
