Jeg har  I dag mod taget 5 opkald fra dette nr nogen der ved Hvem det er?? Tog den ikke da jeg ikke kendte nummeret og kunne se det kom fra udlandet..

Called twice at the same Day and im from Denmark so i didn't Pick up

Received two calls showing this number on a blau.de handy. Glad I missed them, thanks for previous comments, reassured not important for me.

this number just called me about 6 times in a row...picked it up on the second time and no one answered, so i hung up...then I search the number with google and found this page and i'm glad i'm not the only one who receives this calls and also the warnings of not calling back.
Thanks for that....I'm from Switzerland and they called me on my business number.

Call received on mobile yesterday (11th May 2014).  Wasn't able to answer.  Didn't recognise number so googled it.  Saw this web-site and figured out it's a scam.  Also started receiving (same time-frame) calls from 02033659755 on my land line - also fake.

I just got a phonecall and I didnt answer. I live in Hungary and it was a Vodafone topup card I bought 3 months ago- I have no idea how they got my number...

Im from Dubai i got a call from this number last night 3 am i answered and they hung up. What the hell is going on ..

Got a call from this number asking for my craigslist post.. said she is a buyer and wanted to meet..

who is call me want know name

I got a call too from this strange number in Ukraine,((

The same on my mobile in Switzerland right now. Two calls the last one as anonymous...

I'm from the US and this number keeps calling my cell phone. The thing is that the only people who know my number are family members.

Mind you, this number called at 11:00 at night here in the US. If it was actually from London like my phone says, it would be like 5 in the morning there.

I added the number to my reject list in my phone. Someone on another site said it was a Skype number, but who knows?

I live in Switzerland. This morning I received a call from a hiden number. The woman said they were a swiss non-profit organization "Les greniers du monde", and she bored me for a few minutes. Ten minutes later, new call from THIS number (in London, according to my cellphone) and it was this organizazion again ! What the f*** is this ? So I sent them to hell... DON'T answer this number.

Got a call from this number, I did not answer. I'm from Miri, Sarawak, Malaysia.

I am from the US.  Number called me 7 times.  I read up on the number on this forum and assumed it was a scam.  The last time they left a message.  It was a friend of mine calling from Peru.  She had been trying to reach me but for whatever reason hadn't bothered to leave a message (probably thinking I would pick up).  At any rate, I am thinking that it is some sort of issue with caller ID, and that people are receiving calls from all sorts of different people.  (Maybe a phone card or a toll system?)

Called several times in a row and there was rap music in the back ground.7 times back to back

I just got a call from this number. It was easy hearing a woman's voice. I am from Ukraine.

I am from CA, USA and got a call from this number at 9.35 p.m. yesterday evening. He asked me who is this...I didn`t answer... just hanged up!

Have got the same phone number calling me today at 9:30 am UTC+5 time Uzbekistan. Two times Unknown and one time 442030510988, was not able to answer.  
According of all comments here it's could be:
1: Someone was calling you for whatever reason (friends, family, business) from VoIP systems or Skype (Internet calls).
2: Can be scam call.
You can answer this caller for your own risk. It's could be scam and it's could be.... Who knows...!

Spam call
