Calls daily__8:00am-10:00am-9:00pm. No msg ever left. I don't have a clue??

Periodicly calls my landline, calls from same number..  Will call several times in a week, then no calls for a couple of months, then calls again.  I have a device that (Person to Person Interceptor ID-highly recomed) shunts these numbers to nowhere so it rings without disturbing me and they can't leave a message.  Before I had this, they would just hang up on the machine.  It's probably the usual suspects, probably a sales call, bill collectors usually leave a message.

Calls from this number started recently, but does not leave message.
We are on National "donotcall" list.

Correction on the (631) area code. It comes back to the New York Mafia, not Chicago.

Ditto! Answer on, leaves no msg. Annoying. Chicago Mafia area code?

We receive calls from this number a minimum of 3 times a day.  If you answer there is no one there, at least not immediately.

Repeated calling all times of the day.  No message.
