Sometimes when I answer the phone there is a very loud metallic sound when someone speaks. The sound only occurs while they are speaking. It is so loud that I can barely hear their voice, and I have to hang up and call them back. The thing I noticed it that I only remember it happening when I answer the phone when I am on my computer. Anyone know about this problem? Is it just a coincidence? I am asking this question mostly for the sake of my curiosity. Thanks.
