White Paper W950
21 June 2006
Preliminary version - PA4
communication system, no matter which phone
they are using. W950 can interact with the following
corporate systems:
• A Corporate switch PABX, (Private Automatic
Branch Exchange), equipped with a mobile
extension port, (like the Ericsson MD110 and
BusinessPhone).
• The mobile centrex service, if provided by the
operator.
• A telephony server located at the operator’s or
customer’s premises.
Feature buttons
The user activates corporate features by selecting
commands from a list, which can be dynamically
sent by the server via an IP link, or pre-configured
by the company’s IT manager, the operator or a
service provider. Each command displays a text
description of the function.
When a command is selected, pre-configured
DTMF tones are used to communicate the desired
function to the server. The phone can even be used
to send data that the user is prompted to provide,
such as the date they will be back from a business
trip. Feature commands and text descriptions have
to be programmed using XML and then imported
into the phone.
Ongoing call features are reached from the active
call view.
Offline commands and corporate telephony set-
tings can be accessed by pressing the ‘corporate
telephony’ icon once a calling card has been set
up. Activating a command will result in an IP packet
being sent to the server.
Routing of corporate calls
If a company uses a PABX, calls must be routed via
the PABX to gain access to corporate features and
resources. W950 can route outgoing calls to the
corporate switch, instead of to the dialled B-party.
To complete a call, the B-number is then sent to
the mobile extension port of the PABX and the call
set-up is completed. This process is completely
transparent to the user.
A user may dial either an internal number, such as,
1234, or a public number, like +468 123 4567.
W950 can be set to bypass the switch for certain
types of calls.
Configuring the phone for the
company
The person responsible for the corporate commu-
nication services defines how the phone shall be
configured. This may be the company's IT man
-
ager, the operator or a service provider. They define
what feature commands shall be displayed in the
phone, how these commands interact with the
PABX and what text is displayed. They also define
how W950 should handle calls to and from the cor
-
porate switch. This is all done in an XML-structured
configuration file, with the extension .pbx. Once
created, this configuration file can be easily
installed onto W950.
To ensure that only authorized personnel have
access to the PABX, approved mobile phone num
-
bers are added to the list of mobile extensions in
the PBX, and only these numbers will be able to
use the facilities available.
