Abstract

A user often receives a busy signal while placing an important phone call to another user. Prior art allows the caller to "camp" on the callee's phone so that the connection can be made as soon as the callee hangs up after the current call. However, the caller needs a method of completing an important call even when the callee is already involved in another call.

Method of Telephone Override for Authorized Users

      A user often receives a busy signal while placing an important
phone call to another user.  Prior art allows the caller to "camp" on
the callee's phone so that the connection can be made as soon as the
callee hangs up after the current call.  However, the caller needs a
method of completing an important call even when the callee is

      This system allows an authorized caller to override a busy
signal and interrupt an active phone conversation with an important
call.  The caller places the call and receives a busy signal.  The
caller then invokes the Call Override Function (COF) which causes the
system to gain access to the active conversation between the intended
callee and the third party.  The conversation is discretely
interrupted, beginning with a familiar series of audible COF tones
which are heard by both parties of the active conversation.  This
warns both parties that they are about to be interrupted by another
user's COF, allowing a few seconds to find an appropriate place to
pause their conversation while the COF tones are being played.  Then
the system plays a friendly annotated message such as, "call
override", or "emergency call".  The system then automatically places
the third party on hold and establishes a connection between the
caller and the callee.  When this conversation is completed (when
either party hangs up), the connection between the intend...
