Requirements
The Cisco Unified CallManager Express integration supports configurations of the following components:
Phone System
•Cisco Unified CallManager Express 4.0.
•A compatible Cisco IOS software version. Refer to the Cisco Unified CallManager Express and Cisco IOS Software Version Compatibility Matrix at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/prod_installation_guide09186a00805acf50.html.
•Cisco Unified CallManager Express feature license.
•Cisco IP phone feature licenses, and Cisco licenses for other H.323-compliant devices or software (such as Cisco VirtualPhone and Microsoft NetMeeting clients) that will be connected to the network, as well as one license for each Cisco Unity port.
•For the Cisco Unified CallManager Express extensions, SIP phones that support DTMF relay as described in RFC-2833. For a list of supported Cisco IP phone models, refer to the Cisco Unified CallManager Express 4.0 Supported Firmware, Platforms, Memory, and Voice Products at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/prod_installation_guide09186a00805f5908.html.
•A LAN connection in each location where you will plug an IP phone into the network.
Cisco Unity Server
•The applicable version of Cisco Unity. For details on compatible versions of Cisco Unity and Cisco Unified CallManager, refer to the SIP Trunk Compatibility Matrix: Cisco Unity and Cisco Unified CallManager at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_device_support_table09186a0080624ba2.html.
•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 appropriate number of voice messaging ports.
Integration Description
The Cisco Unified CallManager Express integration uses the LAN to connect Cisco Unity and the phone system. The Cisco Unified CallManager Express also provides connections to the PSTN. Figure 1 shows the connections.
Figure 1 Connections Between the Cisco Unified CallManager Express Router and Cisco Unity
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)
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.
When forwarding calls to greetings, Cisco Unity uses the original redirected number, not the last redirected number. For example, when A calls B and forwards the call to C whose phone forwards to voice mail, the call will go to the voice mailbox for B.
Integration Functionality
The Cisco Unified CallManager Express 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)
Integrations with Multiple Phone Systems
Depending on the version, Cisco Unity can be integrated with two or more phone systems:
•Cisco Unity 4.0 and 4.1 can be integrated with a maximum of two phone systems at one time. For information on and instructions for integrating Cisco Unity with two phone systems, refer to the Dual Phone System Integration Guide at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/integuid/multi/itmultin.htm.
•Cisco Unity 4.2 and later can be integrated with two or more 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 at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/integuid/multi/multcu42.htm.
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.
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.

|
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.
|
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.
The Number of Voice Messaging Ports That Will Only Dial Out, and Not Answer Calls
Ports that will only dial out and will not answer calls 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.
Typically, these voice messaging ports are the least busy ports.
Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity 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 Message Notification, do not send calls to it.
Preparing for Programming the Phone System
Record your decisions about the voice messaging ports to guide you in programming the phone system.
Programming the Cisco Unified CallManager Express Phone System
For details on programming the Cisco Unified CallManager Express router for the integration with Cisco Unity, refer to the "Configuring Voice Mail Integration for Cisco Unified CME for SIP Phones" chapter of the Cisco Unified CallManager Express 4.0 Configuration Guide for SIP Phones at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_configuration_guide_chapter09186a00806ba5bd.html.

•In Internet Explorer, go to http://<Cisco Unity server name>/web/sm.
•Double-click the desktop shortcut to the Status Monitor.
•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, refer to the "Subscriber Template Call Transfer Settings" section in the Cisco Unity Administrator Help.
Step 2 Under Transfer Type, click Supervise Transfer.
Step 3 Set the Rings to Wait For field to 3.
Step 4 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.
Changing the Settings for an Existing Integration

Appendix: Using Alternate Extensions and MWIs
Alternate Extensions
In addition to the "primary" extension that you specify for subscribers, you can assign subscribers up to nine alternate extensions. (The primary extension is the one that you assign to each subscriber when you create his or her subscriber account; it is listed on the Subscribers > Subscribers > Profile page.)
Reasons to Use Alternate Extensions
There are several reasons that you may want to specify alternate extensions for subscribers. For example, if you have more than one Cisco Unity server that accesses a single, corporate-wide directory, you may want to use alternate extensions to simplify addressing messages to subscribers at the different locations. With alternate extensions, the number that a subscriber uses when addressing a message to someone at another location can be the same number that the subscriber dials when calling. You may also want to use alternate extensions to:
•Handle multiple line appearances on subscriber phones.
•Offer easy message access on direct calls from a cell phone, home phone, or phone at an alternate work site (assuming that the phone number is passed along to Cisco Unity from these other phone systems). In addition, when such phones are used as alternate extensions, and are set to forward to Cisco Unity, callers can listen to the subscriber greeting, and leave messages for the subscriber just as they would when dialing the primary extension for the subscriber.
Tip To reduce the number of requests from subscribers who want alternate extensions set up for multiple cell phones, home phones, and other phones, give subscribers class of service (COS) rights to specify their own set of alternate extensions. (See the Subscribers > Class of Service > Profile page.) With proper COS rights, a subscriber can specify up to five alternate extensions in the Cisco Unity Assistant—in addition to the nine that you can specify on the Subscribers > Alternate Extensions page in the Cisco Unity Administrator.
•Enable URL-based extensions in Cisco Unity for an integration with a SIP phone system.
How Alternate Extensions Work
Before you set up alternate extensions, review the following list for information on how alternate extensions work:
•Alternate extensions cannot exceed 30 characters in length. By default, each administrator-defined alternate extension must be at least 3 characters in length, while subscriber-defined alternate extensions must be at least 10 characters.
You can use the Advanced Settings tool in Tools Depot to specify a minimum extension length for the extensions entered in the Cisco Unity Administrator and the Cisco Unity Assistant. Refer to the Advanced Settings Tool Help for details on using the settings. Respectively, the settings are Administration—Set the Minimum Length for Locations, and Administration—Set the Minimum Length for Subscriber-Defined Alternate Extensions.
•You can control whether subscribers can use the Cisco Unity Assistant to view the alternate extensions that you specify in the Cisco Unity Administrator. To do so, see the Subscribers > Class of Service > Profile page. The Subscriber-Defined Alternate Extension table displays the alternate extensions that the subscriber adds.
•Neither the Cisco Unity Administrator nor the Cisco Unity Assistant will accept an extension that is already assigned to another subscriber (either as a primary or alternate extension), or to a public distribution list, call handler, directory handler, or interview handler. Cisco Unity verifies that each alternate extension is unique—up to the dialing domain level, if applicable—before allowing either an administrator or a subscriber to create it.
•All alternate extensions use the same transfer settings as the primary extension.
•In many cases, Cisco Unity can activate a message waiting indicator (MWI) for an alternate extension. However, depending on the phones and phone systems involved, some additional phone system programming may be required to set this up.
Setting Up Alternate Extensions
Do the applicable procedure to add, modify, or delete alternate extensions:
•To Add Administrator-Defined Alternate Extensions
•To Modify or Delete Alternate Extension(s)
To Add Administrator-Defined Alternate Extensions
Step 1 In the Cisco Unity Administrator, go to any Subscribers > Alternate Extensions page.
Step 2 In the Administrator-Defined Alternate Extensions table, enter an extension in any row. When entering characters in the Alternate Extensions table, consider the following:
•You can enter an extension up to 30 characters in length. (SIP integrations can use up to 30 alphanumeric characters.)
•Each extension must be unique—up to the dialing domain level, if applicable.
•Enter digits 0 through 9. Do not use spaces, dashes, or parentheses.
•For SIP integrations, you can also enter a valid alias for a SIP URL. For example, if the URL is SIP:aabade@cisco.com, enter aabade. Do not use spaces.
•Rows are numbered as a convenience. You can enter alternate extensions in any order, and you can have blank rows.
Step 3 Repeat Step 2 as necessary.
Step 4 Click the Save icon. Alternate extensions are enabled for all rows in the table.
To Modify or Delete Alternate Extension(s)
Step 1 In the Cisco Unity Administrator, go to any Subscribers > Alternate Extensions page.
Step 2 Do any of the following:
•To modify an extension, change the extension in the Alternate Extensions table.
•To delete extensions, check the check boxes next to the alternate extensions that you want to delete.
•To remove all alternate extensions listed in the table, click Select All.
Step 3 Click the Save icon.
Step 4 Repeat Step 2 and Step 3 as necessary.
Note You can run the Cisco Unity Bulk Import wizard when you want to add alternate extensions for multiple subscribers at once. When you do, the Cisco Unity Bulk Import wizard appends the new alternate extensions to the existing table of alternate extensions, beginning with the first blank row.
Alternate MWIs
You can set up Cisco Unity to activate alternate MWIs when you want a new message for a subscriber to activate the MWIs at up to 10 extensions. For example, a message left at extension 1001 can activate the MWIs on extensions 1001 and 1002.
Cisco Unity uses MWIs to alert the subscriber to new voice messages. MWIs are not used to indicate new e-mail, fax, or return receipt messages.
Setting Up Alternate MWIs
Cisco Unity can activate alternate MWIs. Note that depending on the phones and phone systems, some additional phone system programming may be necessary. Refer to the installation guide for the phone system.
To enable alternate MWIs for extensions, do the following procedure for each subscriber who needs alternate MWIs.
To Set Up Alternate MWIs for Extensions
Step 1 In the Cisco Unity Administrator, go to the applicable Subscribers > Subscribers > Messages page.
Step 2 Confirm that the Use MWI for Message Notification check box is checked.
Step 3 Click the Add button located beneath the MWI Extensions table to add a row to the table. By default, the first row in the table contains an "X" to indicate the primary extension assigned to a subscriber. If you want one more extension and do not need to activate the MWI on the primary extension, you can also modify the first row.
Step 4 Enter the applicable extension in the Extension field of the table. MWIs are automatically enabled for all rows in the table. When entering characters in the MWI Extensions table, consider the following:
•Enter digits 0 through 9. Do not use spaces, dashes, or parentheses.
•Enter , (comma) to insert a one-second pause.
•Enter # and * to correspond to the # and * keys on the phone.
Step 5 Click the Save icon.
Step 6 Repeat Step 3 through Step 5 as necessary.
Note You can run the Cisco Unity Bulk Import wizard when you want to set up alternate MWIs for multiple subscribers at once.
To change or delete alternate MWIs for extensions, do the following procedure.
To Modify or Delete Alternate MWIs
Step 1 In the Cisco Unity Administrator, go to the applicable Subscribers > Subscribers > Messages page.
Step 2 Do either of the following:
•To modify an extension, change the extension in the MWI Extensions table.
•To delete extensions, check the check boxes next to the rows that you want to delete in the MWI Extensions table, and then click the Delete button.
Step 3 Click the Save icon.
Step 4 Repeat Step 2 and Step 3 as necessary.
