Note
While integrating the Cisco Unity Connection with Cisco Unified Call Manager through a SIP trunk uncheck the Synchronize guest time to host option for Unified Communications product line in Virtualized environment. This enables the Unified Communications to synchronize with their clock to external NTP servers.

Requirements

The Cisco Unified CM Express SIP trunk integration supports configurations of the following components:

Phone System

Unity Connection Server

Centralized Voice Messaging

Unity Connection supports centralized voice messaging through the phone system, which supports various inter-phone system networking protocols including proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS. Note that centralized voice messaging is a function of the phone system and its inter-phone system networking, not voicemail. Unity Connection supports centralized voice messaging as long as the phone system and its inter-phone system networking are properly configured. For details, see the “Centralized Voice Messaging” section in the “Integrating Cisco Unity Connection with the Phone System” chapter of the Design Guide for Cisco Unity Connection, Release 14 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/14/design/guide/b_14cucdg.html .

Integration Description

The Cisco Unified Communications Manager (CM) Express SIP trunk integration uses a LAN to connect Unity Connection and the phone system. The Cisco Unified Communications Manager Express router also provides connections to the PSTN.



For a list of supported versions of Cisco Unified CM Express that are qualified to integrate with Unity Connection through a SIP trunk, see the Compatibility Matrix for Cisco Unity Connection at http://www.cisco.com/c/en/us/support/unified-communications/unity-connection/products-device-support-tables-list.html.

Call Information

The phone system 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)

Unity Connection uses this information to answer the call appropriately. For example, a call forwarded to Unity Connection is answered with the personal greeting of the user. If the phone system routes the

call to Unity Connection without this information, Unity Connection answers with the opening greeting.

Integration Functionality

The Cisco Unified CM Express SIP trunk integration with 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; Unity Connection identifies a user based on the extension from which the call originated; a password may be required)

  • Identified user messaging (Unity Connection automatically identifies a 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 Unity Connection is installed as Cisco Business Edition—on the same server with Cisco Unified Communications Manager—Unity Connection cannot be integrated with multiple phone systems at one time.

When Unity Connection is not installed as Cisco Business Edition, Unity Connection can be integrated with two or more phone systems at one time. For information on and instructions for integrating Unity Connection with multiple phone systems, see the Multiple Phone System Integration Guide for Cisco Unity Connection, Release 14 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/14/integration/multiple/b_cuc14intmultiple.html.

Planning the Usage of Voice Messaging in Unity Connection

Before programming the phone system, you need to plan how the voice messaging ports are used by Unity Connection. The following considerations 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.

    For a Unity Connection cluster, each Unity Connection server must have enough ports to handle all voice messaging traffic in case the other server stops functioning.

  • The number of voice messaging ports that answer calls.

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

The following table describes the voice messaging port settings in 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.
Server

(When a Unity Connection cluster is configured)

Select the name of the Unity Connection server that you want to handle this port.

Assign an equal number of answering and dial-out voice messaging ports to the Unity Connection servers so that they equally share the voice messaging traffic.

Answer Calls Check this check box.
Caution 
All voice messaging ports connecting to the Cisco Unified CM server must have the Answer Calls check box checked. Otherwise, calls to Unity Connection may not be

answered.

Perform Message Notification

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

Send MWI Requests

Check this check box to designate the port for turning MWIs on and off.

Allow TRAP Connections

Check this check box so that users can use the phone as a recording and playback device in Unity Connection web applications.

Determining the Number Voice of Messaging Ports to Install

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

  • The number of calls Unity Connection answers when call traffic is at its peak.

  • The expected length of each message that callers record and that users listen to.
  • The number of users.
  • The number of calls made for message notification.
  • The number of MWIs 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 Unity Connection web applications to play back and record over the phone.)

  • The number of calls that use the automated attendant and call handlers when call traffic is at its peak.
  • Whether a Unity Connection cluster is configured. For considerations, see the Considerations for a Unity Connection Cluster section.

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.

Determining the Number of Voice Messaging Ports to Answers Calls

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

If your system is configured for a Unity Connection cluster, see the Considerations for a Unity Connection Cluster section.

Determining the Number of Voice Messaging Ports to Dials Out

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

  • Notify users by phone, pager, or email 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 Unity Connection web applications.

If your system is configured for a Unity Connection cluster, see the Considerations for a Unity Connection Cluster section.


Caution
In programming the phone system, do not send calls to voice messaging ports in Unity Connection that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Send MWI Requests, do not send calls to it.

Considerations for a Unity Connection Cluster

If your system is configured for a Unity Connection cluster, consider how the voice messaging ports are used in different scenarios.

When Both Unity Connection Servers are Functioning

  • A hunt group is configured to send incoming calls first to the subscriber server, then to the publisher server if no answering ports are available on the subscriber server.

  • In Cisco Unity Connection Administration, the voice messaging ports are configured so that an equal number of voice messaging ports are assigned to each Unity Connection server. This guide directs you to assign the voice messaging ports to their specific server at the applicable time.

  • The number of voice messaging ports that are assigned to one Unity Connection server must be sufficient to handle all of the voice messaging traffic for the system (answering calls and dialing out) when the other Unity Connection server stops functioning.

    If both Unity Connection servers must be functioning to handle the voice messaging traffic, the system do not have sufficient capacity when one of the servers stops functioning.

  • Each Unity Connection server is assigned half the total number of voice messaging ports.

    If all the voice messaging ports are assigned to one Unity Connection server, the other Unity Connection server cannot answer calls or to dial out.

  • Each Unity Connection server must have voice messaging ports that answer calls and can dial out (for example, to set MWIs).

When Only One Unity Connection Server is Functioning

  • The hunt group on the phone system sends all calls to the functioning Unity Connection server.

  • The functioning Unity Connection server receives all voice messaging traffic for the system.

  • The number of voice messaging ports that are assigned to the functioning Unity Connection server must be sufficient to handle all of the voice messaging traffic for the system (answering calls and dialing out).

  • The functioning Unity Connection server must have voice messaging ports that answer calls and can dial out (for example, to set MWIs).

    If the functioning Unity Connection server does not have voice messaging ports for answering calls, the system cannot answer incoming calls. Similarly, if the functioning Unity Connection server does not have voice messaging ports for dialing out, the system cannot dial out (for example, to set MWIs).

Step 17

Minimize the Cisco Unity Connection Administration window.

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

Step 18

Sign in to the Real-Time Monitoring Tool (RTMT).

Step 19

On the Unity Connection menu, select Port Monitor. The Port Monitor tool appears in the right pane.

Step 20

In the right pane, select Start Polling. The Port Monitor displays which port is handling the calls that you make.

Testing an External Call with Release Transfer

Procedure

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 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 ring back tone means that 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 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 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 Unity Connection are successfully integrated for turning on MWIs.

Testing Listening to Messages

Procedure

Step 1

From Phone 1, enter the internal pilot number for 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 Unity Connection, which correctly interpreted the information.

Step 3

Confirm that you hear the recorded name for the test user (if you did not record a name for the test user, you hear the extension number for Phone 1). Hearing the recorded name means that 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 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.

Setting Up Supervised Transfer on Cisco Unity Connection

Procedure

Step 1

In Cisco Unity Connection Administration, on the Edit Transfer Rule page for the test user, in the Transfer Type field, select Supervise Transfer.

Step 2

In the Rings to Wait For field, enter 3.

Step 3

Select Save.

Step 4

Minimize the Cisco Unity Connection Administration window.

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

Adding New User Templates for Multiple Integrations

When you create the first phone system integration, this first phone system is automatically selected in the default user template. The users that you add after creating this phone system integration is 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 assign users to the new phone system. You must add the new templates before you add new users who are assigned to the new phone system. For details on adding new user templates, or on selecting a user template when adding a new user, see the User Templates section of the “User Attributes” chapter of the System Administration Guide for Cisco Unity Connection, Release 14, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/14/administration/guide/b_14cucsag.html.
