Buzzing on the phone line

Buzzing phone lines can be a multitude of problems. The prior post that I saw for you stated that the person on the other end did not hear the buzzing. This tells me that you have a cordless phone. If this is the case first try cycling through the channels listening each time for a clear channel. If that does not work consider changing the battery in the hand set. If you have been experiencing lessend battery life " talk time" this can cause buzzing as some phones loose transmit and recieve strength. Always consider the price of a new phone compared to the parts for an old one which may have a few other defects.
