Do any of you guys have your phone number linked to Microsoft or Xbox Live? They ran a "Hello World" promotion recently. I thought that this might be it.

Same thing Hello World from (02) 9313 1320. Looks like an autodialler set up - google verboice

Hello World

These bloody mongrels are the lowest parasites human society produce right up there, sorry, down there with dog sh*t.

Same thing with my phone

Just rang me also noticed my location turn on? It's this a possible hacker?

Had the same call, garbled sound and then hung up. hate these things, usually don't answer if I don't know the number. got caught as wasn't looking.

Rang me in Brisbane 9.12 pm 20/5/14 with garbled message and hung up.

Yes got the same message "Hello World" at Noosa.

I got a call from this number at 10:43 am today and I'm on the do not call register...

Just had a missed call from this number, guessed it was a spam/scam call from the number...annoying :/

Got the same just now. Indecipherable speech then hung up. Sounds like a robot (as in a dialer robot) phishing for valid numbers. Having said that there seems to be lots and lots of these calls all happening within the last 24 hours. Grr. Some people also report getting another call shortly after from a "Private" Number. It is quite possible it is a spoofed or faked caller ID.

Had a missed call, no message left..

Yep just had the same thing happen to me here in Brisbane.

Just got a call from this number! Hung up and tried to ring back and it's disconnected! Annoying!!!!

I also had the "hello world" call.

rcvd numerous calls at odd times like 7.20am, I don't answer it though.

Had this number call. Who the hell is it. Then ring back and not connected.

This number called me at 8.27 a.m today 21 May 2014 and I missed it on my mobile. When I returned the call it would not answer twice.
02 52525256 I presume is a N.S.W number.

Missed the call and when I called back 2 mins later got a message saying number not connected
