Robocalls and caller ID spoofing are more than just annoyances-they’re real threats that disrupt business communications, erode customer trust, and create compliance headaches. To tackle these issues, the STIR/SHAKEN Solution framework was developed, giving businesses and telecom providers a powerful way to verify caller identities and block fraudulent calls.

Today, secure and authentic communication isn’t just a nice-to-have-it’s essential. Implementing STIR/SHAKEN helps reduce spam, protects your brand’s reputation, and ensures your legitimate calls reach customers, all while supporting regulatory compliance. As the demand for trustworthy voice communication grows, adopting STIR/SHAKEN is now a must for any business that wants to stay protected and maintain customer confidence.

Understanding the Basics: What Is STIR/SHAKEN?

STIR/SHAKEN is a set of standards designed to stop caller ID spoofing by making sure callers are who they say they are. Here’s how it works: when a call is made, telecom providers attach a digital signature-kind of like a virtual stamp of approval-using certificates from trusted authorities.

When the call reaches the recipient’s carrier, that digital signature can be checked to confirm the caller’s identity. It’s a lot like how websites use SSL certificates to show they’re secure and authentic. This way, you can trust that the number showing up on your phone is actually who it claims to be.

Why STIR/SHAKEN Matters for Business Communication

Caller ID spoofing isn’t just a hassle for individuals-it can seriously impact businesses as well. When scammers use fake numbers, it can damage your brand’s reputation, lower the chances of your calls being answered, and even get your business numbers blacklisted.

That’s why having a STIR/SHAKEN solution in place is so important. By verifying your caller information, you show customers that your business is trustworthy and professional.

This is especially valuable for call centers, sales teams, and support departments. With STIR/SHAKEN authentication, your calls are less likely to be blocked or ignored, helping you connect with customers more reliably and maintain their confidence in your brand.

How STIR/SHAKEN Works: A Simplified View

Let’s make the STIR/SHAKEN authentication process easy to understand by breaking it into three simple steps:

1. Caller Identity is Verified and Signed

When you make a call, your phone company checks to make sure you’re really the person you say you are. If everything checks out, they attach a digital “seal of approval” to your call.

2. Call Travels Through the Network

Your call, along with its digital signature, makes its way through the telecom network to the person you’re calling.

3. Caller Identity is Confirmed

When the call reaches the recipient’s phone company, they check the digital seal. If it’s valid, the call gets marked as “Verified” so the person you’re calling knows it’s really you on the line.

Levels of Attestation in STIR/SHAKEN

Every call comes with an “attestation level,” which is basically a trust rating from your phone provider:

Full Attestation (A)

Your provider knows exactly who you are and confirms you have the right to use the number you’re calling from. This is the gold standard for trust.

Partial Attestation (B)

The provider knows you, but can’t fully confirm you’re allowed to use that specific number.

Gateway Attestation (C)

The provider can’t verify who you are or if you should be using the number-they’re just passing the call along.

If you want your calls to be trusted and answered, it’s best to work with carriers who can give you full attestation. That way, your calls show up as legitimate and trustworthy to your customers.

Implementing STIR/SHAKEN: What You Need to Know

Absolutely! Here’s a more conversational, human-friendly rewrite:

1. Pick a Provider That’s STIR/SHAKEN-Ready

Start by choosing a telecom or VoIP provider that fully supports STIR/SHAKEN. Make sure they handle everything from issuing certificates to verifying identities and signing your calls.

2. Know What You Need to Prove

Your provider needs to confirm your identity and verify that you have permission to use the phone numbers you’re calling from. Be ready to provide documentation and complete a quick verification process.

3. Let Your Provider Handle Certificates

Certificates, which are like digital ID cards for your calls, are managed by a central authority. You usually won’t need to deal with these yourself-just make sure your provider is authorized to get and use them for you.

4. Keep an Eye on Your Call Reputation

A solid STIR/SHAKEN solution should give you tools to see which of your calls are being verified and how they’re rated. Look for providers that offer easy-to-use dashboards and real-time alerts, so you can stay on top of your call reputation.

STIR/SHAKEN for Call Centers and Enterprises

Big companies and call centers solution usually juggle lots of phone numbers and work with several carriers. That’s why a centralized STIR/SHAKEN solution matters-it ensures your team properly signs, verifies, and keeps every outgoing call compliant, no matter where it begins.

Some solutions even integrate with call analytics tools, enabling detailed visibility into:

  • Verification status
  • Attestation level
  • Call performance metrics

This helps businesses align telecom strategy with operational goals.

Future of STIR/SHAKEN and Evolving Standards

The telecom world is constantly changing, and STIR/SHAKEN is evolving right along with it. In the future, we can expect these protections to cover even more types of calls and new use cases, such as:

International Calls

Right now, STIR/SHAKEN mainly covers domestic calls, but there are plans to expand these protections globally.

Rich Call Data (RCD)

Soon, businesses may be able to include things like their logo or extra branding info with verified calls, making calls even more trustworthy and recognizable.

Keeping up with these changes is essential if you want to stay compliant and keep your customers happy in the long run.

Final Thoughts: Is STIR/SHAKEN Worth It?

Definitely! With growing expectations from regulators, telecom authorities, and customers, adopting STIR/SHAKEN authentication just makes sense. It’s not only a powerful way to cut down on spam and spoofed calls, but it also helps your business stand out by making sure your calls are trusted and more likely to be answered.

Whether you’re a VoIP provider or a business that makes a lot of outbound calls, having a strong STIR/SHAKEN solution should be a key part of your telecom strategy.
