Received a call from this number on 25MAR2009 at 12:23PM CDT.  I didn't answer the phone, but when I dial this number it says "The number you have called is invalid.  Please hang up and try your call again."

Called me twice the evening of the 31 May CET, and I have a Danish phone number. Left no message.

this phone number calls with one ring and hangs up...day and night...couple of times a day.  Finally called it back and it is an "invalid number".

received a call from 919-378-4000 but I did not respond as I was on another call at the time, I called it back and it was invalid. My cell phone immediately started doing things it has not done before, it reboots itself. Battery is charged and twice when trying to make a call my phone would reboot itself.

It was called to me thru relay service, but I was unavailable to respond and no message was left for me.
