When my answering machine answered, they hung up without leaving a message.
Their caller ID was the same as their phone number: 253-236-2698
I think it's the same scammers who used to repeatedly call me from 253-382-9923
I called this number back from my Skype phone so they couldn't trace it back (hopefully) because I wanted to see who answered, and I got a robo-voice immediately offering to remove my phone number within 72 hours if I"d just leave them my number, but I won't leave them my real number as I believe they'll just sell it to other call-scam-telemarketers as a live number that actually has someone there.
