Call Information

The phone system sends the following information through the data link:
• 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
• 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.

• 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

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.
Table 1 Settings for the Voice Messaging Ports
Field Considerations
Uncheck this check box to disable the port. When the port is disabled, calls to the port get a ringing tone but are not answered. Typically, the port is disabled only by the installer during testing.
Answer Calls Check this check box to designate the port for answering calls. These calls can be incoming
calls from unidentified callers or from subscribers.

integrations)
AMIS Delivery
(available with the AMIS licensed feature only)
Check this check box to designate the port for making outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. Cisco Unity supports the Audio Messaging Interchange Specification (AMIS) protocol, which provides an analog mechanism for transferring voice messages between different voice messaging systems.
This setting affects outbound AMIS calls only. All ports are used for incoming AMIS calls. Because the transmission of outgoing AMIS messages may tie up voice ports for long
periods of time, you may want to adjust the schedule on the Network > AMIS > Schedule page so that outgoing AMIS calls are placed during closed hours or at times when Cisco Unity is not processing many calls.
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. Assign TRAP Connection to the least busy ports.
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 and e-mail clients 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 and e-mail clients.
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 Dialout MWI, do not send calls to it.

Note You can use alternate extensions to create multiple line appearances, enable easy message access from
cell phones, and simplify addressing messages to subscribers at different locations in Cisco Unity. Enabling alternate MWIs lets Cisco Unity turn MWIs on at more than one extension. For details, see the
“Appendix: Using Alternate Extensions and MWIs” section on page 19.
