Chapter 7 Configuring Voice Mail
Configuring the Voice-Mail Application
This configuration is required for Cisco Unified CME and Cisco Unified Communications Manager
(SRST mode).
Configuring the Voice-Mail Application
After the Cisco Unity Express software is installed on the system, the voice-mail application that ships
with Cisco Unity Express must be configured using the procedures described in this section. The
application is enabled by default.
To configure the voice-mail access and operator telephone numbers, see “Configuring SIP Triggers for
the Applications” on page 39 or “Configuring JTAPI Triggers for the Applications (Cisco Unified
Communications Manager Only)” on page 43.
The commands can be used in both EXEC and Cisco Unity Express configuration modes.
Sharing Ports Among Applications and Triggers
One of the parameters that you may configure for the voice-mail and auto-attendant applications is the
maximum number of callers who can concurrently access the application at any specific time. This
parameter, maxsessions, is limited by the number of ports on the Cisco Unity Express module. (See
“Recording a Prompt File” on page 29 for the number of ports on your module.) For Cisco Unified
Communications Manager, the ports are configured using the ctiport command (see “Configuring JTAPI
Parameters (Cisco Unified Communications Manager Only)” on page 22).
Consider your expected call traffic when assigning the number of ports to an application. One
application might need more available ports than another, but each application must have at least one
port available for incoming calls.
Suppose, for example, that your module has four ports and you assign four to the voice-mail application
maxsessions and four to the auto-attendant maxsessions. If four callers access voice-mail
simultaneously, no ports will be available for auto-attendant callers. Only when zero, one, two, or three
callers access voice-mail simultaneously will at least one port be available for auto-attendant.
Suppose, instead, that you assign three to the voice-mail maxsessions and three to the auto-attendant
maxsessions. At no time will one application use up all the ports. If voice-mail has three active calls, one
caller can access auto-attendant. A second call to auto-attendant will not go through at that moment.
Similarly, you must assign the maxsessions parameter to each application trigger, which is the telephone
number that activates the application’s script. The value of the trigger’s maxsessions cannot exceed the
application’s maxsessions value.
Required Data for This Procedure
The following information is required to configure the default voice-mail application:
• Application name: voicemail
• Maximum number of subscribers who can access voice-mail simultaneously
