Cisco Systems 4 Manual De Usuario

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 depends on numerous factors, including:

Extension

Enter the extension for the port as assigned on the phone system.

Enabled

Check this check box to enable the port. The port is enabled during normal operation.

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.

Message Notification

Check this check box to designate the port for notifying subscribers of messages. Assign 
Message Notification to the least busy ports.

Dialout MWI

Check this check box to designate the port for turning MWIs on and off. Assign Dialout MWI 
to the least busy ports.

AMIS Delivery

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.
