Who called from 3215740530

Phone rang twice.  I picked up and said hello twice before they hung up.  I suspect it is a telemarketing company that uses a system which dials multiple numbers at the same time and when someone picks up, that first call is transferred to a rep.  Then the system disconnects all the other line even though they might have been picked up.

Called at 11:48am on 2/25/08.   No message received.    Call apparently from Melbourne FL.   I suspect telemarketer, no proof.

Three rings pick up no one there , on the do not call nationwide list ?

321-574-0530, CALLS TWICE A DAY EVERY DAY. WHEN RETURNED, "NOT A WORKING NUMBER?"
