Call Authentication Trust Anchor (CATA)

Call Authentication Trust Anchor (CATA) is a security measure used in phone networks to verify that incoming calls are genuine and originate from legitimate sources. Think of it as a trusted reference point that helps prevent scam calls and caller ID fraud. When a call is received, CATA checks the caller's identity against this trusted anchor to confirm its authenticity. This process enhances call security and trust, ensuring users aren't misled by fake or malicious calls. In essence, CATA acts as a reliable safeguard to protect both network providers and callers from deception.
