We get calls from this number almost daily.  Since we are a business we do not answe the phone with a "hello"   but state our business name,  I think this is an automated system -- it hangs up by itself after a brief period if I don't say anything.

I am received a call on my mobile (in Australia) from this number too but didn't answer as it looked suspicious.  I heard on the radio that dodgy high charged calls to your phone are coming from numbers that start with +20 so I'm definitely staying away from it either way.

I actually answered and spoke to a real person (at least I think so).
I was told it is an Australian online search company that helps Australian businesses to perform better in local listings and searches.
When I questioned them where they got my number from, they referred to a public listings on the internet.
I thanked and hung up straight after.

I've had two missed calls from this phone number over the last week. Like others I haven't answered yet - If they call next time I think I'll answer and try and find out who it is.

Received a call from this number to Australian mobile, answered it but didn't hear anything. Won't be answering again!
