Project Description

We are looking for someone who can develop a system that can unmask caller id of blocked calls. For better understanding of what we want I will try to give you a pratical example.

Our goal is to have a system that can do the following:

A (cellphone or landline) calls B (another phone user) with blocked caller id, B rejects the call and it will be forwarded to an asterisk box (or something) that can be capable to show the hidden number of A.
