The Electret Mic Volume Control Box goes in between the phone and the handset. The adjustment potentiometer reduces the transmitter volume on the handset. It doesn't amplify.

This device can also be useful in reducing ambient noise and solving paging feedback problems. A Noise Cancelling Handset is usually better in these situations but if we can't make one for your phone, this is a viable alternative.
