I have been getting dozens of scam calls each week - usually from a phone number in the same exchange as the number I called. Occasionally their spoofer breaks and the number comes across as an international number "+12905550127" instead of as "290-555-0127". I rarely answer (sometimes I am expecting a call and answer). I have multiple phones in various exchanges so I recognize the pattern. The numbers are also on the "do not call" list but laws don't stop crooks.
