These spoofed calls are usually malicious attempts to sell products or services without subscriber consent, or to take money from the receiver – referred to as fraudulent robocalling.
In 2019, users in the United States experienced close to 60 billion fraudulent robocalls, causing subscribers to stop answering their phone unless the caller ID was from a reputable party. This has been destroying the trust in voice communications, as well as the reputation of legitimate businesses trying to reach their customers.
The Federal Communications Commission (FCC) created an industry-wide initiative to require all telecommunications service providers to incorporate a new technology standard named STIR (Secure Telephony Identity Revisited) and SHAKEN (Secure Handling of Asserted Information Using Tokens). This implementation aims to ensure that calling numbers are not spoofed, reducing fraudulent robocalls.
All small service providers (over the top providers) have until June 30, 2022 to implement STIR/SHAKEN standard within their networks, in accordance with this FCC announcement.
