Integration Description
The Nortel SL-100 integration sends call information and MWI requests through the data link, which is an RS-232 serial cable that connects the phone system and the master TIMG unit. Voice connections are sent through the T1 digital lines between the phone system and the TIMG units. The TIMG units communicate with the Cisco Unity server through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 1 shows the required connections.
Figure 1 Connections Between the Phone System 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.
Integration Functionality
The Nortel SL-100 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)
Supervised Transfer for Calls
When supervised transfer is enabled and a caller hangs up while being transferred to another phone, the called phone will ring briefly even though there is no call. If the ringing phone is answered, there will be no call, only dead air will be heard.
Integrations with Multiple Phone Systems
Cisco Unity 4.2 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 for Cisco Unity 4.2 at http://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, to set message waiting indicators (MWIs), to make AMIS deliveries, 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.
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 MWIs that will be activated when call traffic is at its peak.
•
The number of AMIS delivery calls.
•
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.
•
Turn MWIs on and off for subscriber extensions.
•
Make outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. (This action is available only with the AMIS licensed feature.)
•
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 Nortel SL-100 Phone System
Instruct the phone system technician to set up the phone system in the manner directed in the following procedure.
To Program the Nortel SL-100 Phone System for a Serial TIMG Integration with Cisco Unity
Step 1
Program the phone lines connecting to the voice messaging ports on the TIMG units as a multiline hunt group.
Make sure that the phone system sends calls only to Cisco Unity voice messaging ports that are set to Answer Calls. Calls sent to a voice port not set to Answer Calls cannot be answered by Cisco Unity and may cause other problems.
Step 2
Enable hookflash transfer capability on each phone line that connects to the voice messaging ports on the TIMG units.
Step 3
Enable caller ID (through the serial data link to the master TIMG unit) on each subscriber extension.
CautionThe phone system just provide caller ID through the serial data link to the master TIMG unit. Otherwise, some integration features will not function correctly.
Step 4
For each subscriber extension, set the call forwarding options to the following:
•
Unrestricted source
•
Forward when the extension is not answered
•
Forward when the extension is busy
The following phone system programming is provided as an example. The specific programming for your phone system may vary depending on its configuration.
