Mobile Extension Service

If you frequently travel outside the office, you will generally have a GSM
mobile phone in addition to your DT390 extension. Once again, without
truly being a group service, the Mobile Extension service may be of use to
you. Its purpose is to allow external users of GSM mobile phones most
particularly to access your company's network, and thus be able to use the
system as if they were internal users. In practice, a Mobile Extension
terminal is managed in the same way as a dummy internal user associated
with the external GSM mobile number.
To process these calls, the GSM mobile telephone connects to a specific
DID number for the facility, which accesses the Mobile Extension server.
By connecting through the public ISDN network, the GSM mobile
telephone is then automatically authenticated by its external calling
number. By default, authentication can be carried out by manually dialling
the dummy internal number associated as well as the corresponding user's
password. Once authenticated, the GSM mobile telephone user may call
any internal or external number, just as if he/she were dialling from the
internal dummy extension. The user's identity that is transmitted to the
called parties is the information for the internal dummy extension.
The mobile GSM telephone user may, in the same way, gain access to all
telephone services to which the internal dummy extension has
authorization to access. The GSM mobile telephone may also be directly
called through the number associated with the internal dummy extension.
This may be used in conjunction with a personal group. However, the GSM
mobile telephone will still retain its regular number.

One of the main features is the Appointment Reminder service, where you
