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.
