Abstract:
A terminal adapter that acts as an interface to allow an analog telephony device to be used to conduct telephony communications with an Internet protocol (IP) telephony system include a user interface that can obtain information from a user. The user interface makes use of the analog telephony device to request information from the user, and to receive input from the user. The user could provide input by depressing the keys of a standard numeric telephony keypad. Alternatively, the user could provide spoken input that is interpreted by the terminal adapter.
