Please tell me what this thing does. The receiver of my landline would get so hot that it burnt my ear. Usually this happens only with a mobile phone. I changed the jack and put in a simple one, which solved the problem. This bizarre thing is the one I took out. It measures about 2 inches by 3 inches.
Here is some information I found about it. Other information was too technical. I couldn't understand it. I was wondering if this could be a tap on my phone. I have basic service, which would not require a sophisticated transistored jack. I realize that something is probably also in the phone, but I haven't been able to get it apart yet. The parts seem to have been glued together.
