Exact same situation. The guy called from the number Google voice gives you when you first get an account, it's a California area code, but then texted me from this number. Why even bother using the voice account if you're going to do that?
Same as the person above! Got a text from this number first (with my first name and sexual comments), then a phone call from a Google voice number; it was a man and he knew my first name. I hung up right away.
