Last month Scientific American noted “Hello, we’ve been trying to reach you about your car’s extended warranty.” After years of seemingly unstoppable scam robocalls, this phrase is embedded into the minds of many of us. Robocalls are an explosive problem because the underlying cost is so low. More than 30 billion robocalls are noted over the last 12 months. Malicious experts are looking to harvest unsuspecting businesses and workers to give up confidential information.

RedShift was among the first solution providers to test and implement an anti-robocall protocol in its cloud UCTM called STIR/SHAKEN. This stands for secure telephony identity revisited/signature-based handling of asserted information using tokens, which the FCC began requiring in 2021. STIR/SHAKEN requires a UC or VoIP field when you’re making a voice call saying, “I am this entity, and I have verified the caller ID.” This allows all enterprises and CPS who are transmitting the VoIP message or call to look at that header message and say, “Okay, I can verify with cryptography that, yes, this actually is the originator [of the call].”
