Called my newly installed home phone today no message left but odd how they found my number considering the only people who have it is my parents..

they called and i answered with the business name i work for and my name. they listened and then hung up

I just missed a call from that number and there was even a message left on my machine - which consisted of about a minute of music by Mozart - maybe it's Mozart trying to call!!

This number keep ringing and if i answered it, they keep hung up or just herd breathing..
