extension number they dial. The automated attendant transfers calls to the 
primary extension. However, with Modular Messaging—MSS and 
Modular Messaging—Exchange (except Exchange 5.5 server), Caller 
Applications can be used to customize the Call Answering behavior for 
each extension. For more information, se
page 6-13.
When a subscriber with multiple extensions sends a voice message to 
another subscriber, and if the recipient wished to call the sender, the call 
will be made to the primary extension of the sender.
As with the primary extension, secondary extension numbers are unique. 
Outcall feature 
support
Secondary extensions do not have an impact on the working of the Call 
Me server and the MWI server. The MWI server will only control the 
lamp state for the primary extension. All outcalls are made using the 
primary extension.
Caller Application 
support
With Modular Messaging—MSS and Modular Messaging—Exchange 
(except Exchange 5.5 server), each secondary extension number may be 
associated with a different front-door Caller Application. 
If a Caller Application is associated with a called extension and the call is 
then redirected to the telephone user interface (TUI), the Caller 
Application is executed instead of any default call handling.
If no Caller Application is associated with an extension, TUI uses the 
default call handling for the mailbox.
Multiple mailboxes per extension
Using Caller Applications, it is possible to achieve coverage for multiple 
mailboxes from a single number. A single-level Caller Application can 
transfer the caller to up to 9 mailboxes. 
Call Answer callers hear “To leave a message for subscriber A, press 1. 
To leave a message for subscriber B, press 2, and so on.” They then hear 
an announcement from the relevant subscriber's mailbox, and can leave a 
message. 
To complete the configuration, administrators must create an association 
that ties the deployed Caller App to a specified extension. This is the 
extension that is dialed to reach multiple mailboxes. 
Even when multiple mailboxes are set up for an extension, subscribers are 
still capable of having their own extension number.
Note: An Enhanced-List Application (ELA) can be configured such 
that calls can be made to the extension number of the ELA
