It is a company ( I can't understand their name) soliciting funds for the March of Dimes. Call the # back (914-290-6339) listen to the recorded message and stay on the line. You will hear a further instruction that if "you do not want to receive calls from them, dial 1".
Get calls from this number several times a week, usually hang up, sometimes just says 'hello' in a deep drawn out voice then hangs up. Is in Westchester, NY I think.
