Direct coupling of telephone volume control with remote microphone gain and noise cancellation
First Claim
1. A method for adjusting the microphone gain of a connected telephone from a remote location comprising the steps of:
- establishing a connection between two or more telephones thereby creating a system of connected telephones;
transmitting a present volume setting of a first telephone to one or more connected telephones in the system; and
adjusting a microphone gain and noise cancellation setting at the one or more connected telephones in accordance with the transmitted volume setting from the first telephone that is received at the one or more connected telephones, the microphone gain and noise cancellation being adjusted in direct proportion to the received volume setting from the first telephone.

Abstract
The present invention creates a method, apparatus and system by which a telephone unit volume control provides instantaneous coupling to and controlling of a connected telephone unit'"'"'s microphone gain and noise cancellation circuitry. With this invention, an increase in the volume control on the first unit, will result in an automatic adjustment of the second unit'"'"'s microphone gain control. This microphone gain adjustment is an amount corresponding to the adjustment of the volume of the first unit. The noise cancellation circuitry on the second unit is adjusted to filter more of the background noise before transmission instead of after the receipt of the signal at the destination telephone.
