STIR/SHAKEN is a new rule in the US, brought it in by the FCC to help combat the rampant increase in robocalls and caller ID spoofing. Here in the UK, the term robocalling isn’t commonly used and is referred to as spam calls. We also don’t get anywhere as near as many calls as people do in the US, hence why it is such a huge issue. STIR/SHAKEN aims to put some extra checks in place, with encrypted certificates.

UniFi Talk

Ubiquiti is said to be working on supporting STIR/SHAKEN soon. An employee commented on a thread on the Ubiquiti Community recently, after users were questioning whether UniFi Talk is compliant at all.

“Hi all, UniFi Talk is compliant with STIR/SHAKEN and all outgoing calls with our service have a B level attestation by default. We are working on a solution for A level attestation for outgoing calls, which will be available in a future Talk application release. In case you have questions about verification results from a third-party service, you can comment here and we will follow up.”



As soon as a call enters the public telephone network, the caller ID is examined against a known list of IDs, the call is then provided with an encrypted certificate to the SIP header which helps it show as known and trusted. If not trusted, the call stands more likelihood of being dropped which can cause a lot of issues. However, this new system presents a lot of challenges, especially for smaller SIP providers.

On the ‘Creator Spotlight’ from a few weeks ago, I spoke to Chris Sherwood from Crosstalk Solutions who has a helpful video explaining what STIR/SHAKEN is and how it affected his SIP business. In that episode, we also discussed STIR/SHAKEN in more detail too.
