Door Phone Service
Your telephone facility may be equipped with a door phone, the
calls from which are usually processed by the attendants, just as
the general calls are for your facility.
According to a right assigned to your extension, you may be
allowed to answer calls from a door phone. This is generally the
case.
The general calls acceptance service previously described, also
manages your ability to assist the attendants by accepting or
declining door phone calls.
A door phone call is presented exactly as any other incoming call
would be.
Notes:
The presentation of a door phone call usually lasts no more
than 30 seconds. After this time frame, the door phone call
will be automatically disconnected. A door phone call may
not be placed on hold, nor may it be transferred.
The door phone is usually logged on by an electrical
mechanism independent from your telephone facility.
