Twilio-Powered Nomorobo Wins FTC Robocall Challenge
Time to read: 1 minute
So how does Nomorobo decide who’s a robocaller, who’s a legal telemarketer and act accordingly– all before your phone rings?
Nomorobo uses conditional call forwarding, powered by Twilio, to cache the potential robocall. From there, it inspects the caller’s call frequency. Let’s say the caller made 3,000 calls in the one minute. Odds are it’s a robocaller, and Nomorobo hangs up on them.
Nomorobo also checks if the caller is on an FTC spam list. If the caller is listed, Nomorobo hangs up on caller. If the caller is on an FTC list as a legal telemarketer, Nomorobo passes on the call. If Nomorobo isn’t sure, it’ll prompt the caller with an audio CAPTCHA to determine if the caller’s human. If they pass the CAPTCHA, their call goes through. If they fail, Nomorobo adds that number to the FTC spam list in realtime.
The whole service takes place in the cloud. There are no infrastructure changes, or hardware required. This was one of FTC’s guidelines for the contest. Creator Aaron Foss said “their number one criteria for the winner was ‘how feasible is it to get this launched, and get people using it as fast as possible.’”
Congrats to Aaron on his big win, and fighting the good fight against Robocallers.
