Who called from 8184573981

Missed call at 10:51 am eastern time.
Dialed the number back,  rang until message "We are sorry we cannot reach the subscriber you are trying to call."

Second random call today in two hours. Same incident before from a 407 area code for Florida.

I got 2 calls from this number and a 3rd labeled "private number" that I suspect is the same caller.  No message was left.  I can't imagine why someone from California is calling me.

Went to voicemail, left no message, just 2 seconds of static.

The same thing with me only the Cali number called me after the Florida (407) number.  I simply don't pick up the calls. If they don't leave a message I block the number.

Automated computer voice claims a recent "survey" qualified me for a free no cost solar panel. Hung up no interest and sounds fishy to me.
