The government is trying to bring an end to annoying robo calls.
The Federal Trade Commission held a nationwide contest for developers to come up with a solution to end the robotic phone calls.
Two men now are splitting a $50,000 prize.
The two developed software that detects robotic calls and hangs up on prerecorded messages before the phone ever rings.
When the software detects a robo call, it prompts the caller to enter a number. If the number is not entered, the call is terminated and the number is blacklisted.
The developer now is waiting for a company to put the idea on the market.
The FTC gets about 200,000 complaints about robo calls each month.
