Call unmasking system

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

My 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 or receive the call and it will be forwarded to an asterisk box (or something like TrapCall App) that can be capable to show the hidden number of A and send an SMS to number of A with details of B(Number phone).

Please bid only if you can complete this project.

Skills: Asterisk PBX, Mobile App Development, Telecommunications Engineering, VoIP
