STIR/SHAKEN: An Understanding the Call Authentication Framework for IP PBX Users

 Did you know that Americans received almost 3.8 billion robocalls in December 2023 alone? A study by YouMail Robocall Index revealed that and that’s not all. Annual nationwide robocall volume increased nine percent in 2023.

STIR/SHAKEN: An Understanding  the Call Authentication Framework for IP PBX Users

In today's time, when robocalls and caller ID spoofing have become more prevalent than ever before, there is an urgent need to address this problem. And the solution to the problem is a framework known as STIR/SHAKEN (Secure Telephony Identity Revisited/Secure Handling of Asserted information using toKENs).

This article explains the framework designed to authenticate and verify caller IDs and its significance for IP PBX users. Read on to know more about it.

What Is STIR/SHAKEN?

STIR/SHAKEN is a set of standards and protocols developed to combat illegal caller ID spoofing, a technique used by scammers and telemarketers to disguise their phone numbers and deceive recipients into answering unwanted calls.

The framework works by digitally signing caller ID information using cryptographic certificates, which are then verified by the recipient's service provider. This verification process ensures the authenticity of the caller's identity, allowing legitimate calls to be authenticated and fraudulent calls to be flagged or blocked.

Benefits of STIR/SHAKEN Framework for IP PBX Users

For users of IP PBX systems, STIR/SHAKEN represents a significant advancement in call authentication and fraud prevention. By implementing STIR/SHAKEN protocols within their networks, IP PBX users can:

1. Enhance Caller Trust: STIR/SHAKEN authentication provides assurance to call recipients that the displayed caller ID is genuine, increasing trust in phone communication and reducing the likelihood of calls being ignored or blocked due to suspicion of fraud.

 

2. Combat Caller ID Spoofing: IP PBX users can leverage STIR/SHAKEN to detect and prevent fraudulent caller ID spoofing attempts, thereby minimizing the risk of falling victim to scams or phishing attacks.

3. Improve Call Quality: By authenticating caller IDs and filtering out illegitimate calls, STIR/SHAKEN helps maintain the integrity of phone communication, ensuring that users receive only legitimate and relevant calls, thus enhancing overall call quality and productivity.

4. Compliance with Regulatory Requirements: As governments and regulatory bodies increasingly focus on combating robocalls and fraudulent phone practices, implementing STIR/SHAKEN protocols can help IP PBX users demonstrate compliance with relevant regulations and industry standards.

5. Integration with Existing Systems: Many IP PBX vendors are actively incorporating STIR/SHAKEN support into their systems, enabling seamless integration and easy adoption for users. By embracing STIR/SHAKEN, IP PBX users can stay ahead of the curve in terms of call authentication and security.

Conclusion

STIR/SHAKEN represents a significant leap forward in the fight against fraudulent and unwanted calls, offering a standardized framework for authenticating caller IDs and combating caller ID spoofing. For users of IP PBX systems, embracing STIR/SHAKEN protocols can yield numerous benefits, including enhanced caller trust, improved call quality, and compliance with regulatory requirements. By staying informed about STIR/SHAKEN and its implications, IP PBX users can leverage this call authentication revolution to bolster the security and reliability of their phone communication infrastructure, ensuring a safer and more trustworthy communication experience for all stakeholders.
