Cisco Unity Messaging Integration

---

Cisco Unity comprises a communications solution that delivers voice messaging and unified messaging in a unified environment.

Unified messaging means that users can manage all message types from the same Inbox. Cisco Unity works in concert with an Exchange server or (for Cisco Unity 4.0 and later) a Domino server to collect and store all messages—both voice and e-mail—in one message facility. Users can then access voice and e-mail messages on a computer, through a touchtone phone, or over the Internet.

For complete, step-by-step instructions on how to integrate Cisco CallManager with the Cisco Unity messaging system, refer to the Cisco CallManager 5.0 Integration Guide for Cisco Unity.

---

Note For information on how to integrate Cisco CallManager with the Cisco Unity Connection messaging system, refer to the Cisco CallManager 5.0 SCCP Integration Guide for Cisco Unity Connection 1.1 or the Cisco CallManager 5.0 SIP Trunk Integration Guide for Cisco Unity Connection 1.1.

System Requirements

The following lists provide requirements for your phone system and the Cisco Unity server. For specific version information, refer to the Cisco CallManager 5.0 Integration Guide for Cisco Unity.

Phone System

•A Cisco IP Telephony applications server that consists of Cisco CallManager software that is running on a Cisco Media Convergence Server (MCS) or customer-provided server that meets approved Cisco configuration standards

•Cisco licenses for all phone lines, IP phones, and other H.323-compliant devices or software (such as Cisco Virtual Phone and Microsoft NetMeeting clients) that will be connected to the network, as well as one license for each Cisco Unity port

•IP phones for the Cisco CallManager extensions

•A LAN connection in each location where you will plug an IP phone into the network

•For multiple Cisco CallManager clusters, subscribers can dial an extension on another Cisco CallManager cluster without having to dial a trunk access code or prefix.

Cisco Unity Server

•Cisco Unity system that was installed and made ready for the integration as described in the Cisco Unity Installation Guide.

•The applicable Cisco Unity-CM TSP installed. For more information on compatible versions of the TSP, refer to the Compatibility Matrix: Cisco Unity Connection, the Cisco Unity-CM TSP, and the Cisco CallManager Express documentation.

•A license that enables the appropriate number of voice-messaging ports.

Integration Description

The integration uses the LAN to connect Cisco Unity and Cisco CallManager. The gateway provides connections to the PSTN. Figure 31-1 shows the connections.

Figure 31-1 Connections Between the Phone System and Cisco Unity

---

Note The following example applies only if the caller goes through the Cisco Unity Auto Attendant. Most other calls are routed directly to the correct voice mailbox. For example, callers who call a subscriber and get forwarded to voice mail go directly to the voice mailbox and can record a voice message. Subscribers who call in to check their voice messages from their own phones, go directly to their voice mailbox and can listen to voice messages.

---

1. When an external call arrives, the Cisco gateway sends the call over the LAN to the machine on which Cisco CallManager is installed.

2. For Cisco CallManager lines that are configured to route calls to Cisco Unity, Cisco CallManager routes the call to an available Cisco Unity extension.

3. Cisco Unity answers the call and plays the opening greeting.

4. During the opening greeting, the caller enters either the name of a subscriber or an extension; for example, 1234.

5. Cisco Unity notifies Cisco CallManager that it has a call for extension 1234.

6. At this point, the path of the call depends on whether Cisco Unity is set up to perform supervised transfers or release transfers. Refer to the Cisco CallManager 5.0 Integration Guide for Cisco Unity 4.0 for more information.

Cisco CallManager SIP Trunk Integration

Cisco Unity Connection 1.1 supports a SIP trunk integration with the Cisco CallManager phone system when the Cisco CallManager phone system has only SIP phones. Refer to the Cisco CallManager 5.0 SIP Trunk Integration Guide for Cisco Unity Connection for more detailed information. The following list describes a few tips that should be performed from the Cisco CallManager Administration side when integrating the Cisco CallManager phone system with Cisco Unity Connection by a SIP trunk:

•Create a SIP trunk that points to Cisco Unity 4.2 and ensure that "Redirecting Number IE Delivery - Outbound" is checked. This instructs Cisco CallManager to send the Diversion Header to Cisco Unity, so you access the correct voice mailbox. Refer to "Trunk Configuration" in the Cisco CallManager Administration Guide.

---

Note Cisco CallManager SIP trunk integration applies to MWI. When you configure the SIP trunk security profile for the SIP voice-messaging trunk, check "Accept Unsolicited Notification." This ensures that MWI will operate properly. You must enable "Accept Header Replacement" if you want to support transfers. This allows "REFER w/replaces" to be passed, which is used for Cisco Unity-initiated, supervised transfers.

---

•Assure that your phones support DTMF Relay as per RFC-2833. Cisco Unity will support both OOB and RFC-2833. For more information on compatible versions of the TSP, refer to the Compatibility Matrix: Cisco Unity Connection, the Cisco Unity-CM TSP, and the Cisco CallManager Express documentation.

•Define a route pattern (for example, 7555) and point that route pattern to the SIP trunk to Cisco Unity. Refer to "Route Pattern Configuration" in the Cisco CallManager Administration Guide.

•Define a voice mail pilot (for example, 7555). Refer to "Cisco Voice-Mail Pilot Configuration" in the Cisco CallManager Administration Guide.

•Define a voice mail profile (for example, VM Profile 1) with the voice mail pilot that you defined in the previous step. Refer to "Voice-Mail Profile Configuration" in the Cisco CallManager Administration Guide.

---

Note Make the voice mail profile that you defined in the last step the system default.

Cisco Unity Cisco CallManager Integrated Mailbox Configuration

When Cisco CallManager release 5.0 integrates with Cisco Unity version 4.0(4) (or later) with Microsoft Exchange, Cisco CallManager administrators can create Cisco Unity subscriber voice mailboxes, one at a time, from the Directory Number Configuration or End User Configuration windows.

---

Note For information on Cisco CallManager integration with Cisco Unity Connection, refer to the Cisco CallManager 5.0 SCCP Integration Guide for Cisco Unity Connection 1.1 or the Cisco CallManager 5.0 SIP Trunk Integration Guide for Cisco Unity Connection 1.1.

---

Requirements

•Cisco CallManager release 5.0(x)

•Cisco Unity release 4.0(4) or later with Microsoft Exchange

•Cisco CallManager Integrated Voice Mailbox asp page (installed on the Cisco CallManager server from the Cisco Unity server)

•RIS Data Collector service that is activated on Cisco CallManager server

Restrictions

•After a mailbox is created, no automatic synchronization of mailbox data happens between Cisco Unity and Cisco CallManager. All changes get synchronized manually on both systems.

•The system does not support creation of Internet, VPIM, AMIS, Bridge, or Domino subscriber mailboxes from Cisco CallManager Administration.

•The system does not support bulk or batch import of Cisco Unity mailboxes by using the Bulk Administration Tool (BAT).

•Creation of Cisco Unity mailbox creates a Cisco Unity subscriber account directly in SQL, so new subscribers can be viewed and updated on the Cisco Unity Administrator when the create mailbox transaction completes.

•A log file records Cisco Unity mailbox transactions that are made by using Cisco CallManager Administration on the Cisco Unity server.

•The system writes associated diagnostic logs to a log file.

•Audit log and diagnostic files do not record the transmission of credentials across the network.

Securing the Voice-Mail Port

When you configure security for Cisco CallManager voice mail ports and Cisco Unity SCCP devices, a TLS connection (handshake) opens for authenticated devices after each device accepts the certificate of the other device; likewise, the system sends SRTP streams between devices; that is, if you configure the devices for encryption.

When the device security mode equals authenticated or encrypted, the Cisco Unity-CM TSP connects to Cisco CallManager through the Cisco CallManager TLS port. When the security mode equals non-secure, the Cisco Unity TSP connects to Cisco CallManager through the Cisco CallManager port.

For interactions, restrictions, and procedures on how to configure security, refer to the Cisco CallManager Security Guide.
