Receiving Calls - Avaya Communication Manager Administrator's Manual

While using an Extension to Cellular cell phone on a business call, the user may hear a beep tone (if
Conference Tone is administered) indicating someone has picked up the office number and is listening in
on the call. Avaya provides that beep tone for security purposes. If a user suspects unauthorized use of the
office number or an enabled Extension to Cellular cell phone, the call should be ended immediately and
the user's station security codes should be changed immediately. If additional security is required,
administer one of Avaya's exclusion features.
Call waiting, call identification, and voice mail
Extension to Cellular allows use of standard cellular features such as incoming call waiting and caller ID.
•
If the cell phone (and network) supports calling number identification, the Avaya server running
Communication Manager delivers the calling number to the cell phone. For internally-originated
calls, the calling number may be presented in either the national numbering plan format (ten
digits), or as an extension fewer than ten digits depending upon how calling number identification
is administered. Some cellular phone networks only pass calling number information in the
national format, while others are more flexible.
•
If the cell phone (and network) supports call waiting, Extension to Cellular can be administered to
deliver a second call to the cell phone while it is busy on another call. The cell phone features (for
example, swapping calls or conferencing calls) may be used to answer the second call and
manipulate the two calls through the cell phone.
Since the cell phone is treated as a local extension on the Avaya server running Communication Manager,
it can be completely integrated with the corporate voice messaging system while retaining its own
cellular service provider voice mail.
•
The office number retains the primary extension on the Avaya server running Communication
Manager.
•
Calls to the office number simultaneously ring the office number and the cell phone. If neither
answer then standard coverage arrangements take effect.
•
As needed, Extension to Cellular can be disabled when not in use in order to ensure the use of the
corporate voice messaging system.
The system administrator can control in-service and out-of-service status of the mapped extensions
through a busy-out and release maintenance capability.

Receiving calls

Extension to Cellular/OPS is a solution for delivering office calls to a cell phone or SIP phone through
the Avaya server running Communication Manager.
With Extension to Cellular/OPS, when a call is made to an office number with a mapped phone, the call is
extended out of the Avaya server running Communication Manager to alert the outside phone. When the
Extension to Cellular/OPS user has the Extension to Cellular/OPS
Extension to Cellular/OPS calls are not delivered.
