Dial Tone Modulation Frequency Action Mechanism

       This article describes a mechanism for managing
touch-tone signals from an incoming phone call so that the touch-tone
signals can be used directly by the recipient of the call in
subsequent processing or a return call.

      With the advent of telephone recorders and phone mail systems,
leaving voice mail on a recorder is a common practice.  It is not
unusual for a person to return to an office or home to find several
messages waiting.  The recipient must write down the phone numbers
while listening to the messages and many times is forced to listen to
one message multiple times to get the caller's number correctly. In
the case of multiple messages, the person called must write down the
caller's number with the caller's name to avoid confusion.  Upon the
recipient writing down the number or memorizing the number, the call
is returned by manually dialing the number.

      This article describes a mechanism allowing the caller to key
in the phone number where the caller can be reached instead of voice
recording the number.  The touch-tone pulse is recorded on the
recipient's system, allowing the recipient to phone the caller
automatically by pressing a predefined key for the call back.  This
saves the callee the inconvenience of writing down the caller's
number and then manually redialing that number.  A service is
established that is co-resident with existing telephone recording
devices.  A recipient's prerecorded message can notify the caller of
the service and how to use the touch-tone signals. The service would
intercept these tones and translate them to their appropriate numeric
value.  The numeric values could then be executed on demand by the
recipient to recreate tone signals.

      The service described herein can be expanded for more
sophisticated key sequences such as pause, pause for a specific
perio...
