There may one day soon be another way to fight those annoying prerecorded phone pitches known as robocalls.

The has announced the winners of its contest to develop a blocking technology for the phone calls.

The contest ended with a tie. The winners are Serdar Danis and Aaron Foss. Each will receive $25,000.

The technologies developed by Danis and Foss involve software that could analyze and filter calls to screen out those being placed from a computer or from someone who has been identified as an unwanted caller.

The logs tens of thousands of complaints each month from consumers about robocalls.

The agency isn't endorsing a particular technology but hopes the challenge will lead to one that can be developed for the marketplace.
