A legitimate enterprise can make an important customer call and still have it treated like a potential scam. When customers cannot confidently identify the caller, even a genuine conversation can become a missed opportunity.
For enterprises that depend on voice communication this is no longer just a telecom inconvenience. It affects customer engagement, fraud exposure, brand reputation and the effectiveness of business-critical communication.
The problem is growing as unwanted and fraudulent calls make consumers increasingly cautious. Hiya's 2026 State of the Call research found that 86% of calls from unknown numbers go unanswered and 73% of consumers believe businesses should identify themselves when calling. The study surveyed more than 12,000 consumers across six countries. (blog.hiya.com)
At the same time voice remains important for enterprise interactions. Hiya's 2025 research found that 42% of consumers preferred voice when communicating with healthcare providers compared with 33% in 2024 while 29% of workers reported increasing their use of voice communication at work. (blog.hiya.com)
This creates a clear enterprise challenge:
How do you make legitimate business calls easier to recognize while making fraudulent impersonation harder to trust?
The answer begins with secure caller identity.
Why Enterprise Voice Communication Needs Stronger Identity
A Phone Number Is No Longer Enough
Traditional caller ID was revolutionary when it became widely available. A recipient could see a number before answering and make a quick decision.
But modern voice networks have introduced a fundamental problem.
A displayed number does not automatically prove who is calling.
Spoofing can make a call appear to originate from a number associated with a legitimate organization. This is particularly dangerous for enterprises whose brands are frequently used as impersonation targets.
The FCC describes STIR/SHAKEN as a mechanism that allows originating providers to securely transmit caller identity information and allows terminating providers to verify that the originating number has not been altered during transmission. (docs.fcc.gov)
That moves caller identity from simple presentation toward authentication.
Enterprises Have More at Stake
Consider a financial institution calling a customer about suspicious account activity.
If the customer ignores the call because the number looks unfamiliar the organization loses an opportunity to communicate about a potentially important issue.
Now consider a healthcare provider calling about an appointment.
Or an insurer calling about a claim.
Or a logistics company coordinating a delivery.
In each case the communication may be legitimate and time-sensitive.
The infrastructure may successfully deliver the call.
But delivery does not guarantee engagement.
Trust determines whether the recipient answers.
Caller Identity Is Becoming Part of Customer Experience
Hiya's research shows the scale of this shift. In its 2026 findings only 14% of consumers immediately answer calls from numbers they do not recognize. (blog.hiya.com)
That means enterprises increasingly need to think about caller identity as part of the customer journey.
The first customer interaction may happen before anyone says a word.
It happens when the phone screen displays the incoming call.
Secure Caller Identity Helps Protect Enterprises From Impersonation
Enterprise Brands Are Valuable Targets
A scammer does not necessarily need to compromise an enterprise's internal systems to exploit its identity.
They may attempt to impersonate the organization through a phone call.
The objective could be to convince a customer to:
Share account information
Reveal authentication codes
Transfer money
Provide personal information
Follow a fraudulent instruction
Trust a malicious caller
The enterprise may not be responsible for the fraudulent call yet its reputation can still suffer.
Identity Spoofing Creates a Two-Sided Risk
There are two victims in an impersonation scenario.
The customer can be targeted by the fraud.
The enterprise can suffer reputational damage because its identity is being abused.
Hiya's 2025 research found that 93% of surveyed IT and security professionals were concerned about bad actors impersonating their business to scam consumers. (blog.hiya.com)
That is why secure caller identity needs to work in both directions.
It should help the receiving network assess whether a caller identity has been authenticated.
It should also make it more difficult for unauthorized parties to present themselves as a legitimate organization.
STIR/SHAKEN Creates Cryptographic Evidence
STIR/SHAKEN uses digital signatures and certificates to create verifiable evidence around caller identity.
The basic model is:
Enterprise call → Originating provider → Authentication → Certificate-backed signature → Terminating provider → Verification
The terminating network can then evaluate the authentication information instead of relying entirely on the caller ID value presented by the originating side.
This does not mean an authenticated call is automatically safe.
It means the network has stronger evidence about identity.
That distinction is critical.
Secure Identity Can Help Enterprises Get More Legitimate Calls Answered
Trust Has a Direct Connection to Engagement
Enterprise voice teams often focus on metrics such as:
Answer rate
Contact rate
Conversion rate
Talk time
Callback rate
Customer satisfaction
Caller identity can influence the first of those metrics.
If customers do not answer the call then every downstream metric becomes irrelevant.
Hiya's 2025 survey found that 48% of consumers never answer unidentified calls while another 32% only sometimes answer them. That means 80% of unidentified calls are unlikely to be answered. (blog.hiya.com)
A Legitimate Call Can Look Suspicious
Imagine a customer has requested a callback from an insurance provider.
The enterprise calls from a number the customer does not recognize.
The customer sees no business identity.
They hesitate.
The call ends.
The enterprise may try again.
The customer may ignore that call too.
The problem was not the sales representative.
It was not the call quality.
It was not even necessarily the timing.
The problem was uncertainty.
Authentication and Caller Presentation Solve Different Problems
This distinction matters.
Network-level authentication can help establish that a caller identity has been cryptographically authenticated.
Customer-facing caller identification can help the recipient understand who is calling.
These are complementary layers.
Think of it as a physical office.
The security system confirms that the person entering has authorized credentials.
The reception desk tells visitors which organization they have arrived at.
One establishes security.
The other establishes context.
Enterprise voice increasingly needs both.
Secure Caller Identity Strengthens Brand Reputation
Customers Associate Calls With the Enterprise Behind Them
When a fraudulent caller impersonates a bank or healthcare provider the recipient may remember the organization name rather than the technical details of the fraud.
That creates a brand problem.
The enterprise may have done everything correctly yet still become associated with a negative experience.
Hiya's 2024 State of the Call research found that 33% of business workers said scammers had used their company name in calls while 25% said scammers had hijacked or spoofed their phone numbers. (blog.hiya.com)
That demonstrates why identity protection has a reputation component.
Trust Is Cumulative
A customer who receives several legitimate calls from a clearly identifiable organization can develop confidence in that communication channel.
A customer who repeatedly receives suspicious calls claiming to represent the same organization may do the opposite.
This creates a trust cycle:
Clear identity → confidence → engagement → positive experience
versus:
Unclear identity → suspicion → ignored calls → reduced engagement
Secure caller identity can help enterprises move toward the first model.
Authentication Supports the Foundation
Enterprise branding by itself is not enough.
A malicious actor could potentially attempt to imitate a business name or number.
Authentication provides a technical foundation for determining whether the underlying caller identity has been authorized.
Hiya's branded caller ID service illustrates this layered approach by using network-level authentication to determine whether calls are eligible to display a registered business identity. (hiya.com)
The broader lesson is important:
Brand visibility should be supported by identity assurance.
Certificate Infrastructure Is an Essential Enterprise Control
Secure Caller Identity Depends on More Than Software
Enterprises may think about caller authentication as a feature inside a communications platform.
Underneath that feature sits a trust infrastructure.
STIR/SHAKEN depends on digital certificates that allow receiving systems to validate cryptographic signatures associated with authenticated calls.
The FCC identifies the certificate governance system as a core part of STIR/SHAKEN because certificates help establish trust in authentication information. (docs.fcc.gov)
This means certificate management becomes part of enterprise voice security.
The Certificate Lifecycle Creates Operational Risk
Certificates need to be:
Issued
Protected
Deployed
Published
Monitored
Renewed
Rotated
Revoked when necessary
A certificate that expires unexpectedly can create an authentication problem even though the enterprise's voice application is functioning normally.
That is why certificate management cannot remain an afterthought.
Automation Makes the Trust Layer More Reliable
Peeringhub provides a carrier-grade STIR/SHAKEN Certificate Authority service supporting certificate enrollment, delegated signing, attestation controls and developer automation. Its ACME API supports certificate issue, renewal and revocation. (peeringhub.io)
The platform also provides Identity Header parsing and certificate inspection capabilities for examining authentication data and certificate details. (peeringhub.io)
For an enterprise voice environment this can create a more structured trust workflow:
Certificate enrollment → Authentication → Verification → Monitoring → Renewal
Instead of relying on individual engineers to track every certificate manually the lifecycle can become part of an automated infrastructure process.
Secure Caller Identity Requires Visibility Across the Call Path
Enterprise Calls Do Not Stay Inside One System
A typical enterprise call may travel through several environments:
Enterprise communication platform → SBC → VoIP provider → Transit carrier → Mobile operator → Customer
Each stage creates a potential trust boundary.
That means an enterprise cannot think about identity only at the moment a call leaves its PBX.
The identity information needs to remain meaningful throughout the communication path.
IP and Legacy Networks Create Additional Complexity
The FCC notes that STIR/SHAKEN works on IP networks and that a non-IP segment anywhere in the call path can create a gap in caller ID authentication. It warns that loss of authentication information can undermine the value of the framework and contribute to improper spam labeling or blocking. (docs.fcc.gov)
This is particularly relevant for enterprises using multiple telecom providers.
A company may have a sophisticated authentication process at the originating point but still encounter downstream problems if identity information is not preserved.
Troubleshooting Requires More Than a Failure Message
Suppose an enterprise call is not authenticated.
The engineering team needs to determine:
Was the Identity Header created correctly?
Which certificate was referenced?
Was the certificate valid?
Was the signature correct?
Was the certificate accessible?
What attestation was applied?
Did an intermediate network alter the call path?
Peeringhub's Identity Header Parser can decode PASSporT information including attestation, origination, destination, x5u, algorithm and signature status. Its Certificate Inspector provides issuer, subject, validity and OCN context. (peeringhub.io)
This gives engineers a more practical diagnostic path.
Call → Identity Header → Certificate → Provider → Verification result
Visibility makes trust operational rather than theoretical.
Enterprises Need a Layered Approach to Caller Trust
Authentication Is Not the Same as Reputation
One of the biggest misconceptions about caller authentication is that a verified identity automatically means a good call.
It does not.
A legitimate organization can make an unwanted call.
A compromised enterprise account could potentially be abused.
A verified identity therefore needs to be one signal within a broader trust framework.
Think in Layers
A mature enterprise voice security model can combine:
Identity: Who is calling?
Authentication: Can the network verify the identity?
Certificate trust: Is the cryptographic credential associated with an authorized provider?
Reputation: How has this calling identity behaved?
Context: Is the call expected by the recipient?
Behavior: Does the calling pattern look normal?
Policy: What should the network do with the call?
This resembles modern cybersecurity.
A user may successfully authenticate into an enterprise system but still trigger additional controls if the behavior appears unusual.
Voice communications can apply the same principle.
Customer-Facing Identity Adds Another Layer
Hiya's research indicates that consumers want businesses to identify themselves and that branded caller ID can help address the gap between legitimate business calls and unidentified calls. (blog.hiya.com)
For enterprises the architecture can therefore look like:
Cryptographic authentication + verified identity + customer-facing context + reputation
That is considerably stronger than a phone number alone.
Comparing Enterprise Caller Identity Approaches
Peeringhub: Trust and Certificate Infrastructure
Peeringhub focuses on the infrastructure layer behind authenticated voice identity.
Its platform provides:
STIR/SHAKEN certificate enrollment
Delegated signing
Attestation controls
Identity Header parsing
Certificate inspection
STI-CR certificate hosting
OCN lookup
Public APIs
ACME certificate automation
Peeringhub describes its ACME implementation as an RFC 8555-based service for automated STIR/SHAKEN certificate lifecycle management. (peeringhub.io)
Its developer tooling also provides reusable utilities for certificate inspection, CSR operations and STIR/SHAKEN certificate issuance. (GitHub)
This approach can suit organizations that already have voice infrastructure and want a dedicated trust layer rather than replacing their communications stack.
Ribbon: Identity Assurance and Call Trust
Ribbon takes a broader approach to identity assurance.
Its portfolio combines STIR/SHAKEN authentication capabilities with broader call trust and reputation functionality.
This can appeal to providers that want authentication integrated with downstream call treatment and reputation decisions.
Hiya: Customer-Facing Caller Identity and Reputation
Hiya approaches the problem heavily from the customer and business engagement side.
Its enterprise offering focuses on branded caller ID and caller reputation. Hiya states that branded calls can display a business name, logo and reason for the call while its network-level authentication helps determine whether calls are eligible for branding. (hiya.com)
Hiya also provides caller reputation visibility to help businesses understand spam labeling and calling performance. (hiya.com)
The Strategic Difference
These approaches solve related but different parts of the trust problem.
Peeringhub: certificate and identity infrastructure.
Ribbon: authentication combined with broader call trust capabilities.
Hiya: customer-facing identity, reputation and engagement.
An enterprise may use different layers depending on its communications architecture.
The important point is that secure caller identity is an ecosystem rather than a single feature.
How Enterprises Can Strengthen Caller Identity
1. Map Every Outbound Voice Path
Document which providers handle enterprise calls.
Identify:
SBCs
VoIP providers
Transit carriers
Cloud communication platforms
International gateways
Mobile termination paths
You cannot protect identity if you do not understand where it travels.
2. Establish Clear Number Ownership
Maintain accurate records connecting business numbers to authorized users and providers.
This is fundamental to responsible attestation.
3. Implement STIR/SHAKEN Where Applicable
For eligible voice environments use authenticated caller identity mechanisms appropriate to the network and jurisdiction.
4. Automate Certificate Lifecycle Management
Monitor issuance, renewal and expiration.
Automate repetitive lifecycle events wherever practical.
5. Protect Private Keys
Private keys should be treated as sensitive credentials.
Access should be controlled and their lifecycle should be monitored.
6. Maintain Public Certificate Availability
Receiving networks need access to the certificates required for verification.
Peeringhub provides STI-CR hosting that can generate public URLs for STIR/SHAKEN certificates. (peeringhub.io)
7. Monitor Caller Reputation
Authentication does not eliminate spam labeling.
Track answer rates, complaints, blocking and reputation signals where available.
8. Add Customer-Facing Identity
Where supported integrate branded caller identity with authenticated calling so customers can understand who is calling.
9. Investigate Authentication Failures
Do not treat failed authentication as a generic network error.
Inspect the Identity Header and associated certificate.
10. Measure Business Outcomes
Track:
Answer rates
Contact rates
Callback rates
Spam labels
Customer complaints
Authentication failures
Conversion rates
The objective is not merely technical compliance.
The objective is trusted communication that produces better customer outcomes.
Why Secure Caller Identity Is a Business Strategy
Secure caller identity sits at the intersection of several enterprise priorities.
Customer Engagement: Customers are more likely to engage when they can understand who is contacting them.
Fraud Prevention: Authenticated identity makes certain forms of spoofing more difficult and provides networks with stronger evidence for trust decisions. (docs.fcc.gov)
Brand Protection: Authentication and identity controls can help reduce the opportunity for unauthorized parties to impersonate an enterprise.
Operational Reliability: Automated certificate management reduces dependence on manual lifecycle processes.
Regulatory Readiness: Caller ID authentication remains an important component of the FCC's broader robocall mitigation framework. (docs.fcc.gov)
Revenue Protection: When legitimate calls are ignored the enterprise loses opportunities to communicate.
Hiya reported in 2025 that one in three workers said their company had lost money because it could not connect by phone while 60% of sales professionals reported losing a deal because of call-related issues. (hiya.com)
The implication is straightforward:
Trust in voice is not just a security metric. It can become a commercial metric.
Conclusion: Secure Caller Identity Is Becoming Enterprise Infrastructure
Enterprise voice communication is entering a new phase.
The question is no longer simply whether an enterprise can place a call.
It is whether the customer can recognize it, trust it and confidently answer it.
That requires more than traditional caller ID.
It requires authenticated identity.
It requires trusted certificates.
It requires reliable certificate lifecycle management.
It requires visibility across the call path.
It requires reputation and behavioral context.
And increasingly it requires customer-facing identity that makes legitimate organizations easier to recognize.
The urgency is visible in consumer behavior. Hiya's 2026 research found that 86% of unknown calls go unanswered while 73% of consumers say businesses should identify themselves when calling. (blog.hiya.com)
For enterprises that depend on voice this creates a direct business challenge.
A trusted call can become a customer conversation.
An unidentified call can become a missed opportunity.
Peeringhub provides infrastructure for the trust layer behind authenticated voice communications with STIR/SHAKEN certificate enrollment, delegated signing, attestation controls, Identity Header parsing, certificate inspection, STI-CR hosting, OCN lookup and API-driven certificate lifecycle management. (peeringhub.io)
Its ACME service is designed for automated STIR/SHAKEN certificate issue, renewal and revocation while its developer tooling provides reusable capabilities for certificate and authentication workflows. (doc.peeringhub.io)
The broader lesson is clear:
Secure caller identity is becoming part of the enterprise customer experience.
Organizations that continue treating caller identity as a backend telecom configuration risk losing the very customers their calls are designed to reach.
The enterprises that build identity into their communications architecture can approach voice differently — not merely as a connection mechanism but as a trusted channel for customer engagement.
