Method and system for generating information-bearing audible tones |
摘要 |
A method and system for generating one of a first and second audible tone in a telephony system including a telephony device responsive to a first signal to generate the first audible tone and responsive to a second signal to generate the second audible tone includes receiving an information signal from the telephony system and a user initiated signal from the telephony device indicating a desire to initiate a call from the telephony device. A processor processes the information signal and the user initiated signal to determine at least one of billing rate information, available services, and service control procedures associated with the desired call and generate one of the first and second signals. A dial tone generator generates one of the first and second audible tones in response to one of the first and second signals, respectively.
