show hidden caller ID which are incomming

How to show hidden caller ID which are calling into a phone. I saw someone demonstrate how to show hidden caller id's / private numbers.

How does he do that, is there a software to do that...

BTW he works for a locl telecom operator and doesn;t want to show how he does that technique... Even if I choose not to show my phone number by hidding it in my phone functions it still shows

Anyone know of this method??

Cheers.

i don't think its allowed
i think its illegal if you can forcefully view private numbers
coz people pay to have their number hidden

What if you want to know who is calling, sometimes it is a nuisance when you receive unnecessary phone calls, how would you know if it is a call you would expect and one which verbally abuses you..

This is not about the legallity of anything it is a technical aspect of it so please keep out any legall issues if you have in mind and please address the technical issue

thanks,

No one can answer this ??

it is impossible unless it is enabled by the operator
it has nothing to do with the phone or firmware or by some tricks,

That is what I am guessing.... also because this guy works at a phone company i think it must have been done the way you mentioned..

I'm suprised there isn't a way you can do this. I'm sure if there was something serious involved the police could check the calls

I'm not sure exactly how it's done, but I believe it involves re-routing the incoming call to a different (and most likely illegal) phone server, which then re-routes the call back to your handset as an unblocked number. There are sites out there that allow this, but due to forum rules and legal reasons, I shan't be listing any URL's.
