ABSTRACT:
A method and system for remotely calibrating a headset telephone with a reliable, accurate and easy to use user interface is provided. This method makes use of the remote programmability of advanced telephone headsets and DTMF signal encoding and permits the customer-user to instigate the calibration procedure with an ordinary telephone call. The invention provides a way for the optimum settings to be transmitted, loaded and stored to the headset, thereby improving the audio quality of telephone headsets by providing adjustment steps for such audio qualities as microphone gain, speaker gain, background noise and echo cancellation, filter functions and diagnostics.
