Abstract

Described is a hardware implementation for telephone answering machines (TAMs) to provide privacy protection mode (PPM) operation with an override capability. The design allows a called party the ability to disable the audible ringing of the receiving phone so that all calls, except those with access to an override password, will be controlled.

Telephone Answering Machine Privacy Protection with Override

       Described is a hardware implementation for telephone
answering machines (TAMs) to provide privacy protection mode (PPM)
operation with an override capability.  The design allows a called
party the ability to disable the audible ringing of the receiving
phone so that all calls, except those with access to an override
password, will be controlled.

      In prior TAM technology, incoming calls would not be prevented
from ringing a phone set.  After a programmed number of rings, the
TAM takes the incoming call so that an outgoing message can be played
to the caller.  Typically, the TAM is used when the called party is
away, or it may be used for call screening.  In some cases the called
party may not wish to be made aware of the incoming call, except
under special circumstances.

      The concept described herein features a TAM implementation that
will give the called party the ability to suppress the audible ring
of incoming calls, when desired.  It does, however, maintain the
ability for the caller to enable the ringing function when the call
is of specific importance.

      The operation of the TAM when in PPM with override is as
follows:
     1.  The user places the TAM device into the PPM, typically by
pressing a button.
     2.  If an incoming call is received while in PPM, the TAM will
suppress the ring voltage to the phone set to prevent audible
ringing.
     3.  The TAM will then take the line offhook and will play a
pre-recorded message such as "I do not wish to be disturbed at this
time, but please leave a message after the tone.  If this is an
emergency, please press the digit '1' on your phone".
      4.  Normally, the caller would leave a message and hang-up.
Since  the called phone did not prod...
