STIR/SHAKEN Anti-Robocall

Real-time STIR/SHAKEN Robocall Blocking

The average worker receives more than 100 unwanted automated unwanted robocalls annually. In 2019  nearly 58 billion robocalls arrived with unwanted offers delivering telemarketing or other promotions. US business lost more than $9.5B in productivity time and theft losses due to robocalls according to published TechRepublic sources, and in 2019 scammers made an average of $430 per successful connection, reported an average more than 250,000 robocall complaints every two weeks, out of which 35,000 are new numbers, according to the FTC.

To limit robocall damage, most wireless carriers are adopting FCC framework of interconnected standards called STIR (Secure Telephony Identity Revisited) and SHAKEN (Secure Handling of Asserted information using tokens). STIR/SHAKEN limits the number and dangerous exploits of robocalls hitting networks by verifying the caller ID number legitimately initiating the call.
