Summary

The provided text outlines a set of critical capabilities available for Twilio users to manage and protect their inbound voice calls, specifically focusing on security and data integrity. Users must first determine if a specific caller ID is flagged as a robocaller or a DTMF error by using the Scout tool within their Twilio call flow. This process is essential before attempting to access the calling number or verify DTMF functionality. Furthermore, security experts are advised to locate the STIRSHAKEN attestation level and assess the risk rating of incoming calls to identify potential spam threats. Finally, users can access calling numbers and manage call flows by using the Scout platform directly. These interconnected features ensure that incoming calls are treated as high-risk and are monitored closely to prevent unauthorized data retrieval or spamming.
