Abstract:
A method for select desired telephone calls that ring a phone, comprising:(a) a microprocessor that executes software in response to interrupts generated by: (1) detection of a ring signal of an incoming call, (2) a mode switch which enables program mode or Caller Select mode, (3) a enter switch which enters a number into a programmed list, and (4) a review switch which enables the review of previous calls, (b) a memory for storage of incoming caller ID data and said programmed list of numbers, (c) a LCD display which displays current and previous caller ID information and telephone numbers, (d) said solid state relay switches which connect the phone to a phone line when desired calls are received, (e) a filter which blocks phone tones from going out on the line during program mode, and (f) a external switch which disables Caller Select mode whereby when in Caller Select mode said phone is connected to the phone line and allowed to ring only if an incoming number matches an entry in a programmed list of numbers and whereby when in Caller Select mode phone numbers are entered into said programmed list by pressing the enter switch or when in program mode by pressing said phone buttons and whereby Caller Select mode can be disabled by an external switch thereby enabling the box to display caller ID and pass all calls to said phone.
