METHOD AND APPARATUS FOR PREVENTING RECOGNITION OF A TELEPHONE DIALING SIGNAL

摘要

METHOD AND APPARATUS FOR PREVENTING RECOGNITION OF A TELEPHONE DIALING SIGNAL A method and apparatus for preventing recognition by a telephone system of a telephone dialing signal which inverts at least a portion of the telephone dialing signal in response to receiving the telephone dialing signal. Consequently, an inverted dialing signal is produced and is combined with the telephone dialing signal. Voice and data signals are unaffected. The telephone dialing signal is then connected to the telephone system and is unrecognizable as a valid number.
