All you need to know

Since the release of Ian Flemming’s Casino Royale in 1953, everyone has loved his “Shaken, Not Stirred” martinis.

Although this may seem inappropriate in telephony, there is indeed a Shake / Shake protocol. Its goal is to prevent caller impersonation which is one of the main means of spam and fraudulent calls.

The Federal Communications Commission has set a deadline for all major carriers to implement the STIR / SHAKEN protocol and file for compliance by June 30, 2021.

While most major carriers are already fully compliant with the FCC’s anti-spoofing protocol, Google Voice subscribers have their own doubts about this.

According to a recent discussion thread on the Google Support Community, a Google Voice subscriber pointed out that he is still receiving robocalls even after implementing the STIR / SHAKEN protocol.

The user also raised concerns about when Google Voice will comply with anti-identity theft standards (STIR / SHAKEN).

However, another user pointed out that the deadline set by the FCC was to submit the relevant information to the Robocall call mitigation database that most carriers do, including Google Voice, did.

In addition, said protocol will enter into force on September 28, 2021 when operators must prevent traffic from service providers that are not part of the Robocall Mitigation Database.

This is the reason why Google Voice users still receive robocalls and even after the protocol goes into effect there are plenty of ways to spoof calls.

Thus, the STIR / SHAKEN protocol is not a permanent solution to the problem of caller impersonation, but is only a preventive measure.

Nonetheless, regular users may still notice some difference when said protocol goes into full effect in September.


Essentially, all of this means that even if your network service provider is STIR / SHAKEN compatible, you can still receive robocalls.

That said, we’ll continue to monitor this for further development and provide you with more details when they become available.
