Who called from 6502132757

Happend to me as well...6:56AM PST. I was sleeping of course and couldn't pick up, but no message was left. I won't call back...

Same thing with me, asked for me by name, and when I said, "This is him", he hung up.

I was at work, and we have offices in CA, so I thought it was someone from the offices calling.

Same as above...called 6:30am EST, hung up as soon as I answered.  What was weird was, 30sec later, my home phone rang, same deal.  Don't have caller-id on the landline, so I can't be sure it was the same caller, but...weird, anyway.

The guy asked for me by my first name and hung up as soon as I asked him to identify himself!

I did not try calling back.

Same thing.  Phone call received on my cell at 06:00 a.m. CST from 650-213-2757.  Asked for me by name and after being abruptly woken (and not too happy) I responded with "Who is this!?".  Hung up.
