Comcast announced that the company has rolled out the nation’s largest landline voice implementation of STIR/SHAKEN-based Verified Caller ID feature in an effort to help protect the company’s Xfinity Voice, Comcast Business Voice, and Business VoiceEdge Select customers from illegal robocall calls and caller ID spoofing. These customers will now display a Verified [V] label in the caller ID when a call is authenticated as not spoofed, meaning we have been able to confirm the call is coming from the telephone number displayed.
YouMail estimates that Americans received nearly 46 billion robocalls nationwide in 2020. With an estimated 129 million American households, that’s enough for each family to receive an average of more than 350 spam calls in one year alone. The industry has developed a key technology to help combat robocalls and caller ID spoofing, which makes possible caller ID authentication like the Verified Caller ID feature in Xfinity Voice and Comcast Business Voice.
The Verified Caller ID feature is based on Secure Telephone Identity Revisited (STIR) and Signature- based Handling of Asserted Information Using toKENs (SHAKEN), which is a protocol that authenticates calls between networks. The technology enables voice providers to “sign” and “verify” caller ID information, thus preventing bad actors from manipulating or “spoofing” caller ID information in an effort to deceive and defraud consumers.
