This number called me 3 times yesterday, 10/11/10, went into my voicemail.  I tried calling back from work just now & it is a AT&T voicemail box.  Whoever is doing these calls is probably reading all these messages about his/her phone number, someone creepy.  Must be preparing for haloween.

I have received phone calls from this number as well, usually two calls within a short time frame.  This is now the second or third time I have received calls (12/17/2010).  Same M.O. as others; calls, but leaves no message.
The calls have been  from 323.229.6017

This is the AT&t cell phone VM # for you to check your messages, lately whenever i call in to check my messages nothing happens, it is dead air, with no messages not even old messages I wanted to keep stored,however at times it was noises on the phone as though someone has been monitoring my calls and or vm's i even heard someone say "HELLO?" and said something like "pulling chains and I'm about to talk about you now" I don't know if he was talking to someone in the background or me? I didn't say anything i just muted my phone and listened, eventually
the call ended. hmmmm? very suspicious!!!

Received 2 early a.m. calls from this number but no message left on my voice mail.  I've had calls from this number many times over the last year but since I don't use my cell that much, I just figured it was someone I don't talk to often.

I didn't recognize the phone # so I let it go to voicemail.  The message left was "I want to f@ck you and kill you."  Very creepy>:(
