摘要

A method of selectively sending a DTMF tone from a terminal to a first or a second destination, wherein the terminal sends a signal comprising at least one DTMF tone to an intermediate module prior to distribution to the intended destination, comprising: receiving the signal at the intermediate module; analyzing the nature of any DTMF tones in a portion of the received signal to determine the intended destination thereof; and sending a DTMF tone corresponding to the DTMF tones in the received signal to the determined destination.
