Following 2 - 4 - AT&T SYSTEM 25 Manual

The Following feature allows users who will be away from their own phones to receive
calls at another phone. Following differs from Forwarding in that the Following feature
is activated from the phone that will be the new, temporary destination for calls, while
Forwarding is generally activated from the phone that normally receives the calls.
To receive calls at another terminal (the "away" terminal), users must sign in their PDC at
that voice terminal. To cancel the request, users may either sign out the PDC from that other
voice terminal or sign in at their own voice terminal (the "home" terminal).
Following is also used for FPDCs. Signing in an FPDC automatically signs out the FPDC at
any other voice terminal. However, signing out an FPDC does not automatically sign in the
FPDC at another terminal.
The following features or call types do not follow a user who signs in at another terminal:
Automatic Intercom calls
Calls ringing on Bridged Access buttons
Directed Night Service calls
DGC Group calls
Message Waiting
Outward/Toll Restriction
Personal Line calls
Signaling
A call unanswered at the away terminal will be directed back to the home terminal unless
one of the following busy conditions exists at the home terminal: (1) it is a multiline terminal
with all SYSTEM ACCESS buttons busy and with no idle coverage receiver, or (2) it is a
single-line voice terminal that is off-hook, has no idle coverage receiver, and has no idle
hunt-to station. If the call is sent back to the home terminal, it can be answered or it can
receive the terminal's hunting or coverage treatment. Once the call is directed back to the
home terminal, it is removed from the away terminal.
When a valid FPDC is dialed, the call will be directed to the terminal where the FPDC is
signed in and will be provided the coverage treatment administered for that terminal. If the
FPDC is not signed in anywhere and if the attendant position is administered to handle these
calls, then the call will be directed to the attendant position. If the FPDC is not signed in,
and if the attendant position is not administered to handle these calls, then the calling party
will receive Reorder Tone.
Either Following or Forwarding, but not both, can be active at a given time for a particular
PDC. Activation of one feature while the other is in effect overrides the other feature. For
information on how to use Forwarding, see the entry titled "Forwarding" on page 2-43.
