What is STIR/SHAKEN? Explained for 2026

STIR/SHAKEN is a framework used to combat caller ID spoofing by verifying the authenticity of calls in voice networks. It plays a critical role in reducing robocalls and ensuring secure communication for businesses. Dialerportal integrates this technology to provide a reliable and secure cloud contact-center solution.

What is STIR/SHAKEN?

STIR/SHAKEN is a set of protocols and standards designed to prevent caller ID spoofing in IP-based voice networks. By authenticating the origin of a call, this framework helps reduce fraudulent calls and enhance trust in telecommunications. It is mandated by regulatory bodies like the FCC to help combat illegal robocalls.

How Does STIR/SHAKEN Work?

STIR/SHAKEN works by attaching a digital signature to each call, verifying its authenticity as it travels through the network. This process involves three main components:

  • Secure Telephony Identity Revisited (STIR): A set of technical protocols for call authentication.
  • Signature-based Handling of Asserted Information Using toKENs (SHAKEN): A framework for implementing STIR in IP-based networks.
  • Authentication and Verification: Service providers authenticate calls using digital certificates, ensuring the caller ID is legitimate.

Why STIR/SHAKEN Matters for Small-Business Phone Systems

For small to mid-sized businesses, STIR/SHAKEN is crucial because it helps maintain customer trust and reduces the likelihood of falling victim to scams. By ensuring calls are legitimate, businesses can focus on providing excellent customer service without the disruption of fraudulent calls. Dialerportal's integration of these protocols ensures your communications are secure.

Common Use Cases

STIR/SHAKEN is particularly useful in scenarios where call authenticity is paramount. Businesses in sectors like finance, healthcare, and e-commerce benefit significantly from its implementation. It helps prevent spoofed calls that can lead to data breaches or financial loss.
