9/7/12, call came in on voicemail from this number. 323-271-4856. no message left on my voicemail though. When I called the number back, it really goes right into some type of automated system or voicemail, which says, "Please leave a message after the beep; I'm sorry, this mailbox is full."
there was no caller ID at this time for the call, on my call list, because when the call came in, my cell phone was powered off. They'd just hit the voicemail, and when I powered my phone on, the screen indicated there was a voicemail. The automated system on my voicemail states the phone number called from, that's how I got and/or know what the number is.
It says on this page: "NANPA: Assigned Montebello, California (Pacific Bell)". What does NANPA stand for? what is that? And this has to be some type of telemarketing call. It's a long distance number for me, and I know nothing about "Montebello, California (Pacific Bell)".
