Some ways to robocalls include filing a complaint, signing up for Nomorobo and buying a robocall-blocking device. Using cell phone apps, such Truecaller and PrivacyStar, helps identify robocalls and block them.
Nomorobo is a free service that works by using an Internet-based VoIP phone service to block unwanted calls. It detects numbers that are on a blacklist of offender numbers and automatically blocks them. Filing a complaint with FTC also helps to avoid receiving robocalls. There are devices that users can buy, such as Digitone Call Blocker Plus and Sentry 2, to avoid robocalls. Plugging these devices into a phone line allows users to blacklist unwanted phone calls.
