Hi I was wondering if anyone can help me with a project I am having problems with. I have had built a telephone ringing system with mp3 player and remote Relay and some delay timers .the system allows me to remotely make a telephone ring and then when I lift the receiver the ringer stops and a message is played from the mp3 player. The problem I am having is with a relay that for some reason sometimes it makes the phone ring like a normal phone is meant to or it can do a constant ring and when the receiver is lifted I get interference. The whole system is run from a 12V Battery. hope this makes sense if you need any more info or photos please feel free to ask Thank you
