IM in Australia right now. I got a call from (08) 6464 1500this morning,  i answered it and there was silence, later they cut the phone...

Just got a call from this number answered and there was silence.

What is the reason for these calls? What are they trying to do?  I just dont get it. I have a friend who lives in Nigeria and over the last few weeks, he has called and 3 different numbers have come up. One is 00111111, then, (02) 8986 9400, and the most recent (08) 6464 1500. The network over there is bad, at times we can't even get through to each other at all. Is it bad network??

Same thing - got a call from this number and said it was disconnected when I tried calling back

I have an acquaintance travelling in Nigeria and he rings frequently.  Sometimes the number comes up as 00111111 and recently the number came up as (08) 6464 1500.  He claims to be calling from his U.K. mobile phone all the time.  I think this must be some sort of network "scam" going on in Nigeria with routing calls through other numbers.If anyone has any other info., please post here.

They called me yesterday, a few times, I first thought it was someone calling from skype?
