The US Federal Communications Commission (FCC) has approved a rule giving carriers authority to block unlawful robocalls, with the goal of fighting this issue. However, there is concern that legitimate calls from Twilio's customers could get blocked, as the new rule may not provide clear guidelines for consumers and businesses. To address these concerns, Twilio is advocating for specific conditions, including consumer notification, opt-out options, regular access to call blocking databases, and a process for filing complaints. The company also supports the FCC's goal of combating unlawful robocalls and has built safeguards into its platform to prevent such calls.
