Why Call Authentication Is No Longer Optional for Enterprises

Jul 30, 2025

In a time when robocalls and spoofing continue to erode customer trust, enterprises face a critical challenge: how to make sure their outbound calls are recognized, verified and, most importantly, answered.

Today, trust begins before someone picks up the phone.

That’s why Somos developed the RealBrand Call Authentication Service — a solution designed not just to meet technical standards, but to help enterprises protect their reputation, reach more customers and build clarity into every interaction.

The Challenge: Trust Is Missing from Too Many Calls

Enterprises that rely on outbound calls, whether for account verification, customer support or critical updates, find it harder than ever to connect. Consumers are inundated with calls from unknown numbers and impersonated brands. As a result, even legitimate calls often go unanswered.

This trust gap doesn’t just affect individual interactions. It affects engagement, brand equity and the overall success of communication strategies.

The Opportunity: Establish the Foundation for Trusted Calling

Enterprises can’t protect what they can’t see. Without clear ownership and verification of their phone number assets, legitimate calls risk being mislabeled, ignored or mistaken for spoofed attempts. That’s where RealBrand Call Authentication delivers immediate value.

At the core of RealBrand is the issuance of Delegate Certificates that assert an enterprise’s verifiable right-to-use (RTU) each individual phone number. This level of authentication goes beyond carrier-level attestation, empowering businesses to validate ownership at the number level and take proactive steps to secure their outbound voice communications.

By authenticating calls at the network level and embedding trusted caller information into each interaction, enterprises lay the groundwork for secure call branding, improved answer rates and stronger customer engagement. RealBrand doesn’t just verify the call, it establishes a foundation of trust for every voice interaction moving forward.

The Outcome: Better Answers, Stronger Connections

RealBrand Call Authentication isn’t just a technical solution; it’s a business advantage. Enterprises using call authentication see:

• Higher answer and engagement rates

• Fewer spoofed calls

• Greater brand trust in the voice channel
  Most importantly, they create a more secure and meaningful communication experience for their customers.
