This unknown number from same exchange as one of my numbers called today. This is a really pathetic new tactic that scammers have started to use... try and use the same exchange to hit all numbers on it for suckers.
Apparently said sucker is supposed to think, "Gosh, that number is REALLY local and that makes it trustworthy... I'll answer it for sure!"
Nope.  I didn't answer, they didn't leave a voicemail, and I added them to my blocklist. "Extreme Call Blocker" FTW.
