Prerequisites
•Calls can be successfully completed between phones on the same Cisco Unified CME router.
•If your voice-mail system is something other than Cisco Unity Express, such as Cisco Unity, voice mail must be installed and configured on your network.
•If your voice-mail system is Cisco Unity Express:
Note When you order Cisco Unity Express, Cisco Unity Express software and the purchased license are installed on the module at the factory. Spare modules also ship with the software and license installed. If you are adding Cisco Unity express to an existing Cisco router, you will be required to install hardware and software components.
–Interface module for Cisco Unity Express is installed. For information about the AIM-CUE or NM-CUE, access documents located at http://www.cisco.com/en/US/products/hw/modules/ps3115/prod_installation_guides_list.html.
–The recommended Cisco IOS release and feature set plus the necessary Cisco CME phone firmware and GUI files to support Cisco Unity Express are installed on the Cisco CME router.
If the GUI files are not installed, see the "Installing Cisco Unified CME Software" section on page 92.
To determine whether the Cisco IOS software release and Cisco CME software version are compatible with the Cisco Unity Express version, Cisco router model, and Cisco Unity Express hardware that you are using, see the Cisco Unity Express Compatibility Matrix.
To verify installed Cisco Unity Express software version, enter the Cisco Unity Express command environment and use the show software version user EXEC command. For information about the command environment, see the appropriate Cisco Unity express CLI Administrator Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps5520/products_documentation_roadmap09186a00803f3e19.html.
–The proper license for Cisco Unified CME, not Cisco Unified Communications Manager, is installed. To verify installed license, enter the Cisco Unity Express command environment and use the show software license user EXEC command.

Information About Voice-Mail Integration
To enable voice-mail support, you should understand the following concepts:
• Cisco Unity Connection Integration
• Cisco Unity Express Integration
• Cisco Unity Integration
• DTMF Integration for Legacy Voice-Mail Applications
• Mailbox Selection Policy
• RFC 2833 DTMF MTP Passthrough
• MWI Line Selection
• AMWI
• SIP MWI Prefix Specification
• SIP MWI - QSIG Translation
Cisco Unity Connection Integration
Cisco Unity Connection transparently integrates messaging and voice recognition components with your data network to provide continuous global access to calls and messages. These advanced, convergence-based communication services help you use voice commands to place calls or listen to messages in "hands-free" mode and check voice messages from your desktop, either integrated into an e-mail inbox or from a Web browser. Cisco Unity Connection also features robust automated-attendant functions that include intelligent routing and easily customizable call-screening and message-notification options.
For instructions on how to integrate Cisco Unified CME with Cisco Unity Connection, see the Cisco CallManager Express 3.x Integration Guide for Cisco Unity Connection 1.1.
Cisco Unity Express Integration
Cisco Unity Express offers easy, one-touch access to messages and commonly used voice-mail features that enable users to reply, forward, and save messages. To improve message management, users can create alternate greetings, access envelope information, and mark or play messages based on privacy or urgency. For instructions on how to configure Cisco Unity Express, see the administrator guides for Cisco Unity Express.
For configuration information, see the "Enabling DTMF Integration Using SIP NOTIFY" section.
Note Cisco Unified CME and Cisco Unity Express must both be configured before they can be integrated.
Cisco Unity Integration
Cisco Unity is a Microsoft Windows-based communications solution that brings you voice mail and unified messaging and integrates them with the desktop applications you use daily. Cisco Unity gives you the ability to access all of your messages, voice, fax, and e-mail, by using your desktop PC, a touchtone phone, or the Internet. The Cisco Unity voice mail system supports voice-mail integration with Cisco Unified CME. This integration requires that you configure the Cisco Unified CME router and Cisco Unity software to get voice-mail service.
For configuration instructions, see the "Enabling DTMF Integration Using RFC 2833" section.
DTMF Integration for Legacy Voice-Mail Applications
For dual-tone multifrequency (DTMF) integrations, information on how to route incoming or forwarded calls is sent by a telephone system in the form of DTMF digits. The DTMF digits are sent in a pattern that is based on the integration file in the voice-mail system connected to the Cisco Unified CME router. These patterns are required for DTMF integration of Cisco Unified CME with most voice-mail systems. Voice-mail systems are designed to respond to DTMF after the system answers the incoming calls.
After configuring the DTMF integration patterns on the Cisco Unified CME router, you set up the integration files on the third-party legacy voice-mail system by following the instructions in the documents that accompany the voice-mail system. You must design the DTMF integration patterns appropriately so that the voice-mail system and the Cisco Unified CME router work with each other.
For configuration information, see the "Enabling DTMF Integration for Analog Voice-Mail Applications" section.
Mailbox Selection Policy
Typically a voice-mail system uses the number that a caller has dialed to determine the mailbox to which a call should be sent. However, if a call has been diverted several times before reaching the voice-mail system, the mailbox that is selected might vary for different types of voice-mail systems. For example, Cisco Unity Express uses the last number to which the call was diverted before it was sent to voice mail as the mailbox number. Cisco Unity and some legacy PBX systems use the originally called number as the mailbox number.
The Mailbox Selection Policy feature allows you to provision the following options from the Cisco Unified CME configuration.
•For Cisco Unity Express, you can select the originally dialed number.
•For PBX voice-mail systems, you can select the last number to which the call was diverted before it was sent to voice mail. This option is configured on the outgoing dial peer for the voice-mail system's pilot number.
•For Cisco Unity voice mail, you can select the last number to which the call was diverted before it was sent to voice mail. This option is configured on the ephone-dn that is associated with the voice-mail pilot number.
To enable Mailbox Selection Policy, see the "SCCP: Setting a Mailbox Selection Policy for Cisco Unity Express or a PBX Voice-Mail Number" section or the "SCCP: Setting Mailbox Selection Policy for Cisco Unity" section.
RFC 2833 DTMF MTP Passthrough
In Cisco Unified CME 4.1, the RFC 2833 Dual-Tone Multifrequency (DTMF) Media Termination Point (MTP) Passthrough feature provides the capability to pass DTMF tones transparently between SIP endpoints that require transcoding or Resource Reservation Protocol (RSVP) agents.
This feature supports DTMF Relay across SIP WAN devices that support RFC 2833, such as Cisco Unity and SIP trunks. Devices registered to a Cisco Unified CME SIP back-to-back user agent (B2BUA) can exchange RFC 2833 DTMF MTP with other devices that are not registered with the Cisco Unified CME SIP B2BUA, or with devices that are registered in one of the following:
•Local or remote Cisco Unified CME
•Cisco Unified Communications Manager
•Third party proxy
By default, the RFC 2833 DTMF MTP Passthrough feature uses payload type 101 on MTP, and MTP accepts all the other dynamic payload types if it is indicated by Cisco Unified CME. For configuration information, see the "Enabling DTMF Integration Using RFC 2833" section.
MWI Line Selection
Message waiting indicator (MWI) line selection allows you to choose the phone line that is monitored for voice-mail messages and that lights an indicator when messages are present.
Before Cisco Unified CME 4.0, the MWI lamp on a phone running SCCP could be associated only with the primary line of the phone.
In Cisco Unified CME 4.0 and later versions, you can designate a phone line other than the primary line to be associated with the MWI lamp. Lines other than the one associated with the MWI lamp display an envelope icon when a message is waiting. A logical phone "line" is not the same as a phone button. A button with one or more directory numbers is considered one line. A button with no directory number assigned does not count as a line.
In Cisco Unified CME 4.0 and later versions, a SIP directory number that is used for call forward all, presence BLF status, and MWI features must be configured by using the dn keyword in the number command; direct line numbers are not supported.
For configuration information, see the "SCCP: Configuring a Voice Mailbox Pilot Number" section or "SIP: Configuring a Directory Number for MWI" section.
AMWI
The AMWI (Audible Message Line Indicator) feature provides a special stutter dial tone to indicate message waiting. This is an accessibility feature for vision-impaired phone users. The stutter dial tone is defined as 10 ms ON, 100 ms OFF, repeat 10 times, then steady on.
In Cisco Unified CME 4.0(3), you can configure the AMWI feature on the Cisco Unified IP Phone 7911 and Cisco Unified IP Phone 7931G to receive audible, visual, or audible and visual MWI notification from an external voice-messaging system. AMWI cannot be enabled unless the the number command is already configured for the IP phone to be configured. Cisco Unified CME applies the following logic based on the capabilities of the IP phone and how MWI is configured:
•If the phone supports (visual) MWI and MWI is configured for the phone, activate the Message Waiting light.
•If the phone supports (visual) MWI only, activate the Message Waiting light regardless of the configuration.
•If the phone supports AMWI and AMWI is configured for the phone, send the stutter dial tone to the phone when it goes off-hook.
•If the phone supports AMWI only and AMWI is configured, send the stutter dial tone to the phone when it goes off-hook regardless of the configuration.
If a phone supports (visual) MWI and AMWI and both options are configured for the phone, activate the Message Waiting light and send the stutter dial tone to the phone when it goes off-hook.
For configuration informations, see the "SCCP: Configuring a Phone for MWI Outcall" section.
SIP MWI Prefix Specification
Central voice-messaging servers that provide mailboxes for several Cisco Unified CME sites may use site codes or prefixes to distinguish among similarly numbered ranges of extensions at different sites. In Cisco Unified CME 4.0 and later versions, you can specify that your Cisco Unified CME system should accept unsolicited SIP Notify messages for MWI that include a prefix string as a site identifier.
For example, an MWI message might indicate that the central mailbox number 555-0123 has a voice message. In this example, the digits 555 are set as the prefix string or site identifier using the mwi prefix command. The local Cisco Unified CME system is able to convert 555-0123 to 0123 and deliver the MWI to the correct phone. Without this prefix string manipulation, the system would reject an MWI for 555-0123 as not matching the local Cisco Unified CME extension 0123.
To enable SIP MWI Prefix Specification, see the "Enabling SIP MWI Prefix Specification" section.
SIP MWI - QSIG Translation
In Cisco Unified CME 4.1 and later, the SIP MWI - QSIG Translation feature extends MWI functionality for SIP MWI and QSIG MWI interoperation to enable sending and receiving MWI over QSIG to a PBX.
When the SIP Unsolicited NOTIFY is received from voice mail, the Cisco router translates this event to activate QSIG MWI to the PBX, via PSTN. The PBX will switch on, or off, the MWI lamp on the corresponding IP phone. This feature supports only Unsolicited NOTIFY. Subscribe NOTIFY is not supported by this feature.
In Figure 17, the Cisco router receives the SIP Unsolicited NOTIFY, performs the protocol translation, and initiates the QSIG MWI call to the PBX, where it is routed to the appropriate phone.
Figure 17 SIP MWI to ISDN QSIG When Voice Mail and Cisco Router are On the Same LAN
It makes no difference if the SIP Unsolicited NOTIFY is received via LAN or WAN if the PBX is connected to the Cisco router, and not to the remote voice-mail server.
In Figure 18, a voice mail server and Cisco Unified CME are connected to the same LAN and a remote Cisco Unified CME is connected across the WAN. In this scenario, the protocol translation is performed at the remote Cisco router and the QSIG MWI message is sent to the PBX.

What to Do Next
After configuring DTMF relay, you are ready to configure Message Waiting Indicator (MWI) notification for either the MWI outcall, unsolicited notify, or subscribe/notify mechanism. See the "SCCP: Configuring a Phone for MWI Outcall" section.
Enabling DTMF Integration Using RFC 2833
To configure a SIP dial peer to point to Cisco Unity and enable SIP dual-tone multifrequency (DTMF) relay using RFC 2833, use the commands in this section on both the originating and terminating gateways.
This DTMF relay method is required in the following situations:
•When SIP is used to connect Cisco Unified CME to a remote SIP-based IVR or voice-mail application such as Cisco Unity.
•When SIP is used to connect Cisco Unified CME to a remote SIP-PSTN voice gateway that goes through the PSTN to a voice-mail or IVR application.
Note If the T.38 Fax Relay feature is also configured on this IP network, we recommend that you either configure the voice gateways to use a payload type other than PT96 or PT97 for fax relay negotiation, or depending on whether the SIP endpoints support different payload types, configure Cisco Unified CME to use a payload type other than PT96 or PT97 for DTMF.
Prerequisites
•Configure the codec or voice-class codec command for transcoding between G.711 and G.729. See "Configuring Phones to Make Basic Calls" on page 165.
