My first call from this number. Caller ID is unknown. Typical robo call as it rings 3 times and hangs up. Government "do not call" is useless for these types of calls. Best not to answer so your number is not flagged as live phone number and a telemaketer calls you back later or the number is sold to another group.
Called again. I did not pick up, they left no message. I used to get 10 or more a week from different numbers. since I now never pick up for unknown callers, I get maybe 2 or 3 a week. Eventually they will hopefully get the idea that no one will ever answer them.
