A phone call can connect instantly yet still fail commercially if the recipient does not trust the number appearing on the screen. When 86% of consumers say they do not answer unidentified calls the economics of caller trust becomes impossible for businesses and telecom providers to ignore. (Hiya Blog)
For enterprises that depend on voice communication every unanswered call can represent a missed sale, delayed payment, abandoned appointment or unresolved customer issue. For telecom providers the challenge is broader: they must help create a calling environment where legitimate traffic can be distinguished from spoofed, fraudulent and unwanted calls.
This is where caller authentication and trusted identity become more than technical security measures. They become part of the economics of modern voice communication.
Caller Trust Has Become a Business Metric
The cost of an unanswered call
Voice communication traditionally focused on connection quality, coverage and call completion. Today there is another critical question:
Will the recipient trust the call enough to answer it?
Hiya's 2026 State of the Call research found that only 14% of consumers immediately answer unidentified calls while 86% do not. The research surveyed more than 12,000 consumers across six countries. (Hiya Blog)
That creates a simple economic chain:
Unrecognized number → lower trust → lower answer rate → fewer conversations → fewer business outcomes
For a sales organization making thousands of calls each month even a small reduction in answer rates can affect revenue efficiency.
Trust influences the value of every call
Consider a customer-service team making 10,000 outbound calls.
If 3,000 calls are answered the organization has 3,000 opportunities to solve problems or generate revenue.
If caller trust improves the answer rate enough to create several hundred additional conversations the underlying telecom investment can generate more business value without necessarily increasing call volume.
Trust therefore influences the return on every outbound call.
Why Caller Identity Is Part of the Trust Equation
A phone number alone is no longer enough
Consumers have become accustomed to receiving spam and fraudulent calls. As a result a number they do not recognize can create uncertainty before the call is even answered.
Hiya reports that 73% of consumers agree businesses should identify themselves through caller ID. (Hiya Blog)
This creates a gap between technical reachability and commercial reachability.
A call may successfully reach a handset but still fail because the recipient chooses not to engage.
Think of caller identity as a digital introduction
In a physical business meeting a visitor is more likely to be welcomed when their identity and purpose are known.
Caller identity works in a similar way.
Authentication provides evidence about where a call originated and whether the caller has authority to use the presented number. STIR/SHAKEN was designed to establish this type of trust through cryptographic authentication and verification. (FCC Docs)
The economic objective is straightforward: make legitimate calls easier to trust while making fraudulent identity claims harder to rely on.
How STIR/SHAKEN Connects Security With Economics
Authentication creates a chain of trust
STIR/SHAKEN allows an originating provider to cryptographically sign caller identity information. A terminating provider can then use the corresponding public certificate to verify the information. The FCC describes this as establishing a chain of trust back to the originating provider. (FCC Docs)
This is important because caller trust cannot depend solely on what a number looks like.
The underlying infrastructure needs mechanisms that allow providers to establish whether the presented identity has been authenticated.
Better trust can support better business outcomes
Twilio's documentation highlights several practical use cases for SHAKEN/STIR including voice notifications, contact centers, sales dialers and AI voice applications. It specifically connects verified identity with improving the reach of outbound calls. (Twilio)
The principle is simple:
Authentication → stronger identity signals → greater confidence → higher probability of engagement
STIR/SHAKEN does not guarantee that a call will be answered. It is one component of a broader trust ecosystem. But it gives carriers and businesses a technical foundation for establishing caller identity.
The Economics of Trust for Telecom Providers
Trust can become a competitive differentiator
For telecom providers the value of caller trust extends beyond individual calls.
A provider that delivers reliable authentication and strong voice protection can potentially offer a better communication experience to its customers.
This matters as businesses increasingly evaluate voice platforms based on more than price and call quality.
They also care about:
Call reachability
Caller identity
Fraud protection
Authentication
Regulatory readiness
Brand reputation
Operational reliability
Security failures have an opportunity cost
Suppose two providers offer similar voice connectivity.
Provider A focuses primarily on basic connectivity.
Provider B combines connectivity with stronger identity authentication, certificate management and trust controls.
If customers increasingly care about whether their calls are recognized and trusted Provider B can create additional value around the same underlying communication channel.
Trust becomes part of the product rather than simply an infrastructure feature.
Certificate Infrastructure Has an Economic Role
Certificates are behind the trust signal
Caller trust does not appear automatically on the recipient's device.
STIR/SHAKEN relies on certificates to establish the cryptographic relationship between the identity presented in a call and the service provider authorized to sign it. (FCC Docs)
That makes certificate operations a business consideration as well as a technical one.
A provider needs to manage certificate issuance, renewal, rotation, publishing and revocation effectively.
Peeringhub's platform is specifically built around STIR/SHAKEN certificate authority services with certificate enrollment, certificate management, signing workflows and developer automation. Its ACME API supports certificate issue, renewal and revocation. (peeringhub.io)
Automation changes the cost equation
Manual certificate operations consume engineering time.
Automation turns repetitive processes into standardized workflows.
Peeringhub supports three management approaches: a web interface, Python-based tooling and an ACME API. This allows providers to integrate certificate operations into their existing infrastructure rather than treating every certificate as a separate manual task. (peeringhub.io)
The economic benefit is straightforward:
Less repetitive administration → fewer operational bottlenecks → more scalable trust infrastructure.
Comparing Approaches to Caller Trust
Peeringhub: Certificate and trust infrastructure
Peeringhub focuses specifically on the certificate authority and developer infrastructure behind STIR/SHAKEN. Its platform combines certificate issuance with APIs, certificate inspection, Identity Header parsing, OCN lookup and lifecycle tooling. (peeringhub.io)
This approach is particularly relevant for providers that want programmable control over their authentication infrastructure.
Twilio: Trusted calling within a communications platform
Twilio integrates SHAKEN/STIR into a broader programmable communications ecosystem. Its documentation shows how authenticated calling can support contact centers, notifications, sales dialers and AI voice applications. (Twilio)
The distinction is important.
Peeringhub is centered on the trust and certificate infrastructure while Twilio places trusted calling within a broader communications platform.
Neither approach eliminates the wider caller-trust challenge. They address different layers of the voice ecosystem.
The bigger lesson
Telecom providers should evaluate trust infrastructure based on how it fits their architecture, operational model and growth strategy rather than viewing authentication as a standalone compliance exercise.
Measuring the Return on Caller Trust
Move beyond certificate metrics
Traditional telecom reporting may focus on call volume, completion rates and network performance.
Caller trust requires additional measurements.
Useful indicators can include:
Answer rates
Unknown-call rates
Spam labeling
Authentication success
Attestation distribution
Certificate validity
Certificate renewal performance
Customer complaints
Conversion from answered calls
These metrics help connect technical infrastructure with commercial outcomes.
Example: Measuring trust as a funnel
Imagine an enterprise making 50,000 outbound calls.
The business can measure:
50,000 calls initiated ↓ Calls successfully connected ↓ Calls recognized or authenticated ↓ Calls answered ↓ Conversations completed ↓ Business outcomes generated
This provides a much clearer picture of where value is being lost.
If connectivity is strong but answer rates remain weak the problem may not be the network. It may be trust.
Conclusion: Caller Trust Has a Measurable Economic Value
Caller trust is no longer simply a reputation issue or a cybersecurity concern. It directly influences whether people answer calls and whether businesses get the opportunity to complete the conversations they are paying to initiate.
With 86% of unknown calls going unanswered according to Hiya's 2026 research the cost of an unidentified or poorly trusted call can be significant. (Hiya)
STIR/SHAKEN provides an important technical foundation by creating a cryptographic chain of trust around caller identity. Certificate infrastructure then becomes a critical part of keeping that trust mechanism operational. (FCC Docs)
For telecom providers the strategic opportunity is to treat caller authentication as an investment in reachability, customer experience and communication value rather than viewing it only as a regulatory requirement.
Peeringhub helps providers build this foundation through STIR/SHAKEN certificate authority services, ACME-based automation, APIs and developer tooling designed for certificate lifecycle management. (peeringhub.io)
