DTMF tones signal to a phone system that a user wants to complete a particular action, sending frequency-based commands to back-end technology. The tones in DTMF technology are “dual-sided” because each key sends two tones, one in high frequency and the other in low frequency. How do Co...
This chapter discusses Dual-Tone Multi-Frequency (DTMF) signaling digital signal processing (DSP) system, which is designed using LabVIEW. DTMF signaling is used extensively in voice communication applications such as voice mail and telephone banking. A DTMF signal is made up of two tones selected...
Data storage area allows wireless communication device user input to be used as a series of dual-tone multi-frequency data (DTMF) tones processed and sent. 无线通信装置在话务信道上发送呼叫始发并可在话务信道上发送DTMF音调. Wireless communication device transmits a call origination in the traffic ...

Dual tone multi-frequency (DTMF) is the sounds or tones generated by a telephone when the numbers are pressed. These tones are transmitted with the voice channel. DTMF is used to control automated equipment and signal user intent, such as the number they wish to dial. Each key has two ton...
Dual-tone multifrequency (DTMF) is a method used to dial telephone numbers or to issue commands to switching systems. DTMF is widely used for telecommunication signaling between telephone handsets and switching centers over analog telephone lines in voice-frequency bands. Advertisements DTMF is used...
Thus, all DTMF tones are blocked before they are recognized.doi:US6408067 B1Jeffrey I. RobinsonUSUS6408067 * 1998年10月29日 2002年6月18日 Iq Systems, Inc. Methods and apparatus for intercepting dual-tone multi-frequency (DTMF) signals and for redialing the intercepted signals with additional ...
Collecting dual-tone multi-frequency (DTMF) digits IBM® Voice Gateway supportsRFC 4733, RTP Payload for DTMF Digits, Telephony Tones, and Telephony Signals. Dual-tone multi-frequency (DTMF) signals are converted into single digit text utterances that are sent to the configured Watson API. ...
The TTR simulator captures DTMF data received by a private branch exchange (PBX) switch and utilizes the instruction set of the TTR being simulated to process the received DTMF signals on the simulated TTR. Diagnostic tools allow step-by-step tracing and recording of the instructions performed by...
