Enhanced User Functionality from a Telephone Device to an IP Network
First Claim
1. A method of providing enhanced user functionality from a telephone device using conventional DTMF electronics, when connected in a plurality of ways to an application of interest on an IP network, comprising the steps of connecting 1 to 4 new key assemblies to the 1 to 4 unused DTMF electronic controls that are supplied in the conventional standard 16 tone DTMF generator electronics, the unused signals generally referred to as 4th column DTMF ABCD signals, that when depressed, generates said signals, optionally adding to the telephone device a plurality of additional keys and tone signal electronics beyond the current 16 tone DTMF standards, that when depressed, generates said additional signals, receiving said unused dialed tone signals in a processor connected to an IP network, converting the unused tone signals to digital IP signals, sending said digital IP signals to the IP network application of interest, providing a means for allowance of use of said digital IP signals in the application of interest.

Abstract
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.

- 5. A method of enhanced keypad labeling of a telephone device with expanded key capacity from the conventional twelve (12) keys to some or all of sixteen (16) keys incorporating some or all of four additional key assemblies for 4th column ABCD DTMF activation, for the purposes of sending enhanced command and control signals, used in communicating with an IP network, comprising a means of maintaining the conventional 12 key labels of 0-9, * and #, and spreading out the English alphabet characters among the keys in a plurality of ways.
