RoboCall Filtering on the Firewall

The solution contains filtering robocalls that are made using VoIP services. The phones that are called will be able to show the IP addresses of the robocallers. Once the IP addresses of Robocallers are known, the IP addresses can be blocked on the firewall of ISPs or telco providers. There is also a need for a central repository that can maintain the IP addresses that are used by Robocallers. This is very similar to current repositories of computer virus signatures. The consumers can report IP addresses of Robocaller, and if an IP address is reported more than 1000 times, it should be blacklisted.
