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

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

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

5. Create the integration. See the Creating an Integration with the Phone System.

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


Note Cisco Unity failover is not available for the integration with a QSIG-enabled phone system.


Requirements

Revised April 7, 2009

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 Server

Cisco Unity installed and ready for the integration, as described in the applicable Cisco Unity installation guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

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

Centralized Voice Messaging

Cisco Unity supports centralized voice messaging by supporting various inter-phone system networking protocols including, for example, proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS. For details, see the "Centralized Voice Messaging" section in the "Integrating Cisco Unity with the Phone System" chapter of the Cisco Unity Design Guide Release 5.x at http://www.cisco.com/en/US/docs/voice_ip_comm/unity/5x/design/guide/5xcudgx.html.

Integration Description

This integration uses a Cisco ISR voice gateway and a LAN or WAN to connect Cisco Unity 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

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

Integration Functionality

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

Call forward to personal greeting

Call forward to busy greeting

Caller ID

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

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

Message waiting indication (MWI)


Note Some phone systems may not support all integration features (such as MWIs). For details, see the application note at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.


Integrations with Multiple Phone Systems

Cisco Unity can be integrated with multiple phone systems at one time. For information on the maximum supported combinations and instructions for integrating Cisco Unity with multiple phone systems, refer to the Multiple Phone System Integration Guide for Cisco Unity 5.0 at http://cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.

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

Before programming the phone system, you need to plan how the voice messaging ports will be used by Cisco Unity. 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, 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 voice messaging ports that are available to answer calls.

Release (blind) transfers that are forwarded back to Cisco Unity 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 that can be set in UTIM, and that are displayed as read-only text on the System > Ports page of the Cisco Unity Administrator.

Table 1 Settings for the Voice Messaging Ports 

Field
Considerations

Enabled

Check this check box.

Answer Calls

Check this check box to designate the port for answering calls.


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

Message Notification

Check this check box to designate the port for notifying subscribers of messages.

TRAP Connection

Check this check box so that subscribers can use the phone as a recording and playback device in Cisco Unity web applications and e-mail clients. Assign TRAP Connection 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 will answer when call traffic is at its peak.

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

The number of subscribers.

The number of ports that will be set to dial out only.

The number of calls made for message notification.

The number of TRAP connections needed when call traffic is at its peak. (TRAP connections are used by Cisco Unity 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 subscribers. Typically, the voice messaging ports that answer calls are the busiest.

You can set voice messaging ports to both answer calls and to dial out (for example, to send message notifications). However, when the voice messaging ports perform more than one function and are very active (for example, answering many calls), the other functions may be delayed until the voice messaging port is free (for example, message notifications cannot be sent until there are fewer calls to answer). For best performance, dedicate certain voice messaging ports for only answering incoming calls, and dedicate other ports for only dialing out. Separating these port functions eliminates the possibility of a collision, in which an incoming call arrives on a port at the same time that Cisco Unity takes the port off-hook to dial out.


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 voice messaging ports that are available to answer calls. If your system uses Cisco Unity auto-attendant transfers, you must provision a larger number of QSIG b-channels than the number of Cisco Unity 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 subscribers by phone, pager, or e-mail of messages that have arrived.

Make a TRAP connection so that subscribers can use the phone as a recording and playback device in Cisco Unity 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, and see the application note that is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.

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

For information on configuring the Cisco ISR voice gateway, see the application note that is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_guides_list.html.


Note If the Cisco Unity SIP Port setting will not be 5060 (for example, 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

In the status bar next to the clock, right-click the Cisco Unity tray icon and click Status Monitor.


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.

Step 2 On the Status 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 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 and that you hear the greeting for the test subscriber. Hearing the greeting means that the phone system forwarded the unanswered call and the call-forward information to Cisco Unity, which correctly interpreted the information.

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

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

Step 9 On the Status 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 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.

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

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

Step 4 When asked whether you want to listen to your message, press 1.

Step 5 After listening to the message, press 3 to 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 are successfully integrated for turning off MWIs.

Step 7 Hang up Phone 1.

Step 8 On the Status 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


Step 1 In the Cisco Unity Administrator, go to the Subscribers > Subscribers > Call Transfer page.

If the name of the test subscriber is not displayed, click the Find icon (the magnifying glass) in the title bar, then click Find, and select the name of the test subscriber in the list that appears.

For more information on transfer settings, see the "Subscriber Template Call Transfer Settings" section in Cisco Unity Administrator Help.

Step 2 Under Transfer Incoming Calls to a Phone, click Yes, Ring Extension For, and confirm that the extension number is for Phone 1.

Step 3 Under Transfer Type, click Supervise Transfer.

Step 4 Set the Rings to Wait For field to 3.

Step 5 Click the Save icon.


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.

Step 2 On the Status 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 or beeps).

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 is supervising the transfer.

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

Step 7 During the greeting, hang up Phone 2.

Step 8 On the Status 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 Delete the Test Subscriber


Step 1 In the Cisco Unity Administrator, go to the Subscribers > Subscribers > Profile page.

If the name of the test subscriber is not displayed, click the Find icon (the magnifying glass) in the title bar, then click Find, and select the name of the test subscriber in the list that appears.

Step 2 In the title bar, click the Delete Subscriber icon (the X).

Step 3 Click Delete.
