mr know it all, nice try!
Bwahahahahahahahaha

I think this is an outbound only line that is an extension from a calling card service or major switchboard.  So for example, lets say your from korean guy, and your making a phone call using a phone card; the phone cards outbound number to wherever he dialed will show up as that number. So it can be potentially anyone whos calling you.

I have pay as you go phone and that number called twice. I don't answer it as it seems that they try to use my minutes, so that I will buy more.

some korean guy

some russian guy calls
