This invention encompasses the utilization of all of the 16 DTMF tone
signals on telephone devices and their use for additional adjunct feature
controls over IP networks that offer a plethora of new options from
telephone devices. Calls on the PSTN only require the 0-9 digits to be
used to complete a call following the North American Numbering Plan and
International Telecommunications Union (ITU) standards. Conventional
telephones electronically have the standard electronics for all 16 DTMF
tone signals, but only 12 are utilized on conventional telephones by the
typical 4 row and 3 column keypad matrix arrangement. In other words, 25%
of the 16 DTMF tones are not being utilized in the public telephone
networks. This invention lays the claims surrounding a 100% utilization
methodology and possible expansion thereof when communicating to an IP
network.
