EC500 Extension to Cellular
Issue 5 October 2002 1665555-233-506
Call Waiting, Call Identification, and Voice Mail
EC500 allows use of standard cellular features such as incoming call waiting and
caller identification.
■ If the cell phone (and network) supports calling number identification, the
Avaya Communications Server delivers the calling number to it. For
internally originated calls, the calling number may be presented in either
the national numbering plan format (i.e. 10 digits) or as a less than 10 digit
extension, depending upon how it 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, EC500 can be
administered to deliver a second call to the cell phone while it is busy on
another call. The cell phone features (i.e. swapping calls, conferencing the
calls) may then be used to answer the second call and manipulate the two
calls at the cell phone.
Since the cell phone is treated as a local extension on the Avaya Communications
Server, it can be completely integrated with the Corporate voice mail system
while retaining its own Cellular Service Provider voice mail. The office number
retains the primary extension on the Avaya Communications Server. 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, EC500 can
be disabled when not in use in order to ensure the use of the Corporate voice mail.
The System Administrator can control in-service and out-of-service status of the
bridged extensions through a busy out and release maintenance capability.
Receiving Calls
EC500 is a solution for delivering office calls to a cell phone through the Avaya
Communications Server.
With EC500, when a call is made to an office number with a mapped XMOBILE
bridge, the call is extended out of the Avaya Communications Server to alert a cell
phone. If the Avaya Communications Server is administered to send calling
number information, then it is presented to the cell phone. When the cell phone
answers the call, the Avaya Communications Server treats it like a local answer of
a physically connected station, and the following is true:
■ Status station of the XMOBILE station shows it off-hook. It shows both the
port used on the outbound loop back trunk group and the other connected
port.
■ Any office number busy indicators tracking the XMOBILE station light up
to show that it is busy.
