RoboCall Firewall

RoboCall Firewall is a unique service that I created to answer the challenge. RoboCall Firewall will screen all incoming calls that the user will choose to screen using my service. Then the caller will get screened by the system. If the caller is a legit caller it will go back to the phone line and if not a "Not in Service" tone and announcement will be heard. And the caller will be listed as RoboCall.
