I have been receiving calls from 910-599-9182/ 973-444-1386/ 614-378-1765/ 720-204-1286 tey never leave a message but call consistantly about every four hours until 10 pm. I only answered one time and they wanted my credit card number so I could claim a prize.

From Credit Card Services wanting to lower my interest rates.  They will not identify further, and they DO call from different numbers.  Requires a "press 1".  Phone company says you shouldn't.  Computers seem to be unable (or unwilling to try) to catch these people.  Someone sells them the service to these numbers.  Wonder why they cannot catch them?  hmmm...

I get calls frequently from this number and they never leave a message.  if you call the number back, it asks you for a pin number!!!

Rang 4 times; picked up and said hello 3 times (phone still on, but no voice). I hung up.
