Hey, just thought I would share a really rough explanation on what you could be experiencing for legitimate calls and 0000.
My example below is for international calls: Say someone in the UK calls someone in NZ.
When you see an incoming call with 0000 on your phone. (Assume the person in UK has not restricted their caller ID). The call could go through numerous ?carriers? before it arrives in NZ. Example: O2 UK calls World XE NZ (UK call routes via British Telecom who route via China Telecom who bounce their NZ destination call traffic to Telstra Australia who send calls to Telecom NZ who then forward onto World XE) .
O2 UK British Telecom China Telecom Telstra Australia Telecom NZ World XE
Somewhere along the line in one or more of the carriers is discarding the Caller ID as it is not necessary for call completion. I don?t want to get too technical and I use this explanation really loosely, but for the above carriers in this example China Telecom, Telstra Australia, Telecom NZ only need to know the ?calling reference at that particular time? for the carrier preceding it and the destination number for World XE user. Some people may see caller ID?s from say 86xxx?xx numbers ? if we apply to the above scenario UK person calls NZ person, there is a good chance that the China Mobile network (which is Chinas international 86xx?xx) is appending the Caller ID field with their number range.
Anyway ? I am a customer of World XE broadband, I?m thinking of going naked DSL package, with the VoIP setup (currently with telecom fixed line). I don?t really use a landline, just came across and saw this post. Hope it helps explains one particular scenario. There are many more that can be explained. (which I don?t really have time for). But for the initial post of blocking SPAM 0000 calls. This would require the co-ordination of a few parties (ie; if the call is originating internationally, co-coordinating with carriers and their sub carriers is a mission) to help track the offender(s). Just my 2c from my experience.
fair enough, I'll live with them for now. I just get realy annoyed because all the ones I get are scammers.
Been watching a heap of Tom Mabe clips on youtube though. I'll have to get something set up to record calls because I've got a few ideas I might try the next time they call me. Might as well have some fun with them.
