Who called from 6504118790

Have been getting calls from this number but I chose not to answer.  Nothing on 800notes about them.  So I called back a couple of times.  Both times the number was busy.  Not sure what it is yet.  The area code is the same as mine.

I received a call from this number in the Caller ID.  I assume 411 can't be a valid exchange, so I didn't answer.

I should add that the Caller ID was "XXXXXXXXXX CA", and I think other numbers using this ID have been associated with Solar referrals.

Got a call earlier today. Caller ID showed XXXXXXXXXXX CA w/ a phone number listed as 650 411-8790. Caller ID looked fungy hence did not pick up. Left no msg.

exact same scenario here -- xxxxxx in caller ID, didn't pick up, no message left on voice mail
