Integration Description
The Cisco Unified Communications Manager (CM) Express (formerly known as Cisco Unified CallManager Express) SIP trunk integration uses a LAN to connect Cisco Unity and the phone system. The Cisco Unified Communications Manager Express also provides connections to the PSTN. Figure 1 shows the connections for a system with a single Cisco Unified CM Express router.
Figure 1 Connections Between the Cisco Unified Communications Manager 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 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 CM Express SIP trunk integration with Cisco Unity provides the following 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; Cisco Unity identifies a subscriber based on the extension from which the call originated; a password may be required)
•
Identified subscriber messaging (Cisco Unity automatically identifies a 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
Cisco Unity 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, see the Multiple Phone System Integration Guide for Cisco Unity 8.x at http://www.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.
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 Cisco Unity Administrator.
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 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.
CautionIn 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 Dialout MWI, 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 Communications Manager Express Phone System for Integrating with Cisco Unity
For details on programming the Cisco Unified CM Express router for the integration with Cisco Unity, refer to the "Integrating Voice Mail" chapter of the Cisco Unified Communications Manager Express System Administrator Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_installation_and_configuration_guides_list.html.
Creating a New Integration with Cisco Unified Communications Manager Express

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 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.
