Abstract
An off-hook condition on the telephone line of the calling party is detected. When the off-hook condition is detected, an automatic dialer is initiated to dial a predetermined code which, when received by computers of the telephone company, will automatically block the transmission of information which identifies the calling party, and more specifically, the telephone number of the calling party.
Claims7
A method for blocking the transmission of identifying information of a calling party on a telephone network, comprising;
- detecting an off-hook condition on the telephone line of said calling party;
- providing an initiating signal on detecting said off-hook condition;
- said initiating signal causing automatic dialing of a predetermined code, said dialed predetermined code being applied to said telephone line of said calling party to thereby block the transmission of identifying information concerning said calling party;
- said predetermined code being automatically dialed before the calling party dials the telephone number of a receiving party;
- said predetermined code being transmitted to a computer of the telephone company which then blocks the transmission of the identifying information;
- the speed of the automatic dialer being high enough so that the action of the automatic dialer is essentially transparent to said calling party;
- said predetermined code being automatically dialed each time said off-hook condition is detected on the telephone line of said calling party.

Apparatus for blocking the transmission of identifying information of a calling party on a telephone network, comprising;
- off-hook detector means having an input and an output, said input of said off-hook detector means being connected to the telephone line of said calling party to detect an off-hook condition on said telephone line of said calling party and to provide and initiating signal on detection of said off-hook condition;
- automatic dialing means having an input and an output, said automatic dialing means input being connected to said off-hook detector means output and said automatic dialing means output being connected to said telephone line of said calling party;
- so that, upon receipt of said initiating signal from said off-hook detector means, said automatic dialing means dials a predetermined code and applies it to said telephone line of said calling party to thereby block the transmission of identifying information concerning said calling party;
- said predetermined code being automatically dialed before the calling party dials the telephone number of a receiving party;
- said predetermined code being transmitted to a computer of the telephone company which then blocks the transmission of the identifying information;
- the speed of the automatic dialer being high enough so that the action of the automatic dialer is essentially transparent to said calling party;
