Who called from 7814571236

We got a call from this number today at 7:11 pm and didn't answer. No voicemail message was left. The caller ID was LEXINGTON MA. When I called back (our number is hidden by default on outgoing calls) I heard nothing but silence. When the caller ID is the name of a town, it's usually a telemarketer. The number will be added to our call blocker.

Caller ID says "Lexington  MA".  They leave no message.

I call back after hours (using *67 to block my number).  I hear about 15 seconds of silence and then it hangs up on me.

So we have a spoofed caller ID and the failure to identify themselves on their outgoing "message".  Smells like a SCAM.
