These callers that leave no message and call repeatedly, here is what is going on:
They call to see if anyone answers. If you answer then they make note of the time of day someone is available to answer the phone at that number. They keep calling to get a much better view as to when someone will answer.
This is valuable information to scammers, telemarketers, etc as they can better use their resources to call only people that have a high probability of answering the phone.
Want this to stop? DO NOT ANSWER CALLS FROM UNFAMILIAR NUMBERS!
Use your answering machine or answering service to screen callers of unknown numbers.
