FCC Mandated Compliance · STIR/SHAKEN

Stop Your Client's Calls Being Labeled Spam Likely.

iCallify’s built-in STIR/SHAKEN framework gives VoIP providers, MSPs, and contact center operators FCC-compliant caller ID authentication — at the platform level, across every tenant.

STIR/SHAKEN Attestation Levels

Full Attestation

Caller ID verified — service provider confirms identity and authorized use of number

✅

Partial Attestation

Call origin verified — provider confirms call originated from customer, number not confirmed

✅

Gateway Attestation

Point-of-entry verified — call entered US from international gateway

✅

All three attestation levels are supported natively in iCallify's operator platform — no third-party middleware required.

FCC Deadline is in effect. The FCC’s Robocall Mitigation Program requires all VoIP providers and intermediate carriers to implement STIR/SHAKEN or file a robocall mitigation plan. Non-compliant operators risk removal from the FCC database and blocking of all call traffic by downstream carriers.

The Compliance Landscape

What STIR/SHAKEN means for your VoIP business

STIR/SHAKEN is the FCC-mandated framework that verifies caller ID authenticity across IP networks — and non-compliance is now a business risk, not just a technical issue.

STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs) are technical standards that digitally sign and verify phone calls as they travel across IP networks.

When a call is made, the originating carrier signs it with a digital certificate. The receiving carrier verifies that signature. If the number checks out, the call displays normally. If not — or if no signature exists — carriers can label it “Spam Likely” or block it entirely.

For VoIP operators, MSPs, and contact center service providers, this means your clients’ legitimate outbound calls can be silently killed — destroying call connect rates, agent productivity, and campaign ROI — if your platform is not properly signing and attesting those calls.

How a STIR/SHAKEN verified call flows

Agent dials outbound call

Call originates from your client's contact center tenant within iCallify.

iCallify signs the call with a PASSporT token

The platform digitally signs the call using a certificate from the SHAKEN PKI (Public Key Infrastructure) and attaches an attestation level.

✓ Attestation A assigned

Call passes through carriers

Intermediate carriers pass the signed SIP Identity header through to the terminating carrier.

Receiving carrier validates signature

The terminating carrier checks the signature against the PKI. Verified calls display the caller ID cleanly.

✓ Verified — displays normally

Without STIR/SHAKEN

No signature = no trust signal. Carrier or SPAM analytics flag the call as suspicious.

Why This Matters Now

Three ways non-compliance hurts your operator business

STIR/SHAKEN is no longer a “nice to have.” These are the real-world consequences for VoIP operators and MSPs who haven’t implemented it.

Client calls get blocked or flagged

Without proper STIR/SHAKEN implementation, your clients' outbound calls — contact center campaigns, sales calls, customer follow-ups — are mislabeled as robocalls or blocked entirely by downstream carriers. This destroys call answer rates and agent productivity.

Impact: Call answer rates drop 60–80% on unlabeled or flagged numbers.

FCC enforcement and database removal

The FCC's Robocall Mitigation Database requires all originating and intermediate VoIP providers to either implement STIR/SHAKEN or file a mitigation plan. Operators not in the database face carrier-level blocking of their entire traffic stream — not just individual calls.

Impact: Removal from FCC database = potential blocking of all traffic by major carriers.

Client churn from poor call performance

Your business clients don't always know why their calls aren't connecting. They just see low answer rates and blame the platform. If your competitors are offering STIR/SHAKEN-compliant calling and you're not, this is a churn risk and a sales obstacle you cannot afford to ignore.

Impact: Compliance becomes a competitive differentiator — and a reason clients leave.

iCallify STIR/SHAKEN Capabilities

Built into the platform. Active across all your tenants.

iCallify implements STIR/SHAKEN at the operator layer — which means every client tenant you onboard benefits automatically. You configure it once. Every client is covered.

01 Full PASSporT Token Signing

Every outbound call originating from your iCallify deployment is digitally signed with a PASSporT token using your carrier-issued certificate from the SHAKEN PKI ecosystem. Attestation level is automatically assigned based on call type and number ownership.

Core Compliance

02 Attestation A, B & C Assignment

The platform intelligently assigns the correct attestation level per call — Full (A) for calls where the number is directly provisioned to the end user, Partial (B) for calls originating from known customers, and Gateway (C) for international ingress points.

Intelligent Routing

03 Multi-Tenant Coverage in One Deployment

As an operator, STIR/SHAKEN is configured at your platform level — not per client. When you onboard a new tenant, they inherit compliance automatically. No additional configuration per client. No manual certificate management per tenant.

Operator-Grade

04 FCC Robocall Mitigation Database Support

iCallify supports all documentation and technical requirements needed for your FCC Robocall Mitigation Database filing. We assist operators in maintaining their database registration and keeping their compliance posture current as FCC rules evolve.

05 Compliance Reporting Dashboard

Operators get a compliance reporting view showing STIR/SHAKEN signing status across all outbound call traffic — per tenant, per campaign, or aggregate. Identify any unsigned calls, certificate expiry alerts, and attestation level distribution.

Visibility

06 White-Label Compliance Positioning

Your clients experience your branded platform as STIR/SHAKEN compliant. Your brand gets the compliance credit. iCallify stays invisible. You can present compliance dashboards and status reports to your own clients under your branding — a strong retention and upsell tool.

Operator Fit

Which operators this is built for

Every type of VoIP operator faces STIR/SHAKEN requirements differently. Here’s how iCallify addresses each scenario.

VoIP Providers & ITSPs

Originating carrier compliance with automatic tenant coverage

As a VoIP provider or ITSP, you are the originating carrier. STIR/SHAKEN compliance is your direct FCC obligation. iCallify implements signing at the platform level, covering all of your downstream clients automatically — with no per-client certificate management overhead.

MSPs & Managed Service Providers

Deliver compliant calling to every business client you manage

Your business clients depend on you to ensure their communication stack is compliant. If their calls are being labeled “Spam Likely,” they come to you for answers. iCallify gives you a STIR/SHAKEN-compliant platform you can deliver to every client under your brand — turning compliance into a value proposition, not a support headache.

Contact Center Operators & BPOs

Protect campaign call answer rates for every client you manage

BPO and contact center operators running outbound campaigns for multiple clients live and die by call answer rates. “Spam Likely” labeling on your client’s brand numbers is a direct revenue impact. iCallify’s STIR/SHAKEN implementation protects your call traffic at the platform level — across every campaign and every client account you run.

Telecom Operators & White-Label Resellers

Maintain your carrier relationships and downstream call delivery

Telecom operators and white-label resellers who pass traffic to downstream carriers need to maintain clean STIR/SHAKEN posture or risk being blocked at the carrier level. iCallify supports intermediate carrier compliance and helps operators maintain their FCC database registration — protecting the entire traffic relationship, not just individual calls.

Platform Comparison

Why iCallify's STIR/SHAKEN is different

Most platforms treat STIR/SHAKEN as a per-client add-on or a third-party middleware problem. iCallify builds it into the operator platform so every tenant is covered from deployment day one.

Frequently Asked Questions

iCallify implements STIR/SHAKEN at the operator platform level — meaning you configure it once, and all client tenants you provision inherit compliant call signing automatically. There is no per-client certificate management or per-tenant STIR/SHAKEN setup. This is a core advantage of the multi-tenant operator architecture: compliance scales with your business without adding operational overhead per client.

"Spam Likely" labeling has two distinct causes: STIR/SHAKEN non-compliance (no call signature) and SPAM analytics engine flags (a separate system used by carriers and analytics providers like First Orion, Hiya, and TNS). iCallify's STIR/SHAKEN implementation addresses the first cause — ensuring your calls are properly signed and verifiable. For SPAM analytics flags on specific numbers, additional remediation steps are needed (number reputation management, call frequency controls, and analytics engine challenges). iCallify's consulting team can advise on both tracks.

STIR/SHAKEN as mandated by the FCC applies specifically to US-based VoIP operators and carriers terminating calls to US numbers. However, similar caller ID authentication frameworks are being adopted globally — Canada has implemented STIR/SHAKEN (mandated by the CRTC), and the UK is progressing with its own equivalent framework. For iCallify operators serving US-based clients or routing calls to US numbers, STIR/SHAKEN compliance is directly applicable. For operators in other regions, we advise building STIR/SHAKEN capability now to prepare for regulatory expansion in your market.

The attestation level (A, B, or C) depends on the relationship between your operator deployment, your clients, and the numbers being used. For calls where the number is directly provisioned to the end user through your platform, Full Attestation (A) is assignable. For calls originating from verified customers using numbers not directly assigned, Partial Attestation (B) applies. Gateway Attestation (C) covers international call ingress. iCallify's platform handles all three scenarios, and the compliance dashboard shows attestation level distribution across your call traffic.

SHAKEN certificates must be issued to authorized parties in the SHAKEN PKI ecosystem — typically the originating service provider (you, as the operator, or iCallify on your behalf depending on your deployment model). During the iCallify deployment and compliance consulting engagement, our team guides you through the certificate acquisition process, including working with a Certification Authority (CA) approved by the ATIS SHAKEN Governance Authority. This is part of the standard operator onboarding process for STIR/SHAKEN deployment.

Yes. iCallify's white-label architecture allows you to expose compliance reporting and call verification status to your clients under your own brand. Your clients see your branded compliance dashboard — not iCallify branding. You can present STIR/SHAKEN compliance as a feature of your platform, use it in your sales process as a differentiator, and provide your clients with the compliance documentation they need for their own regulatory requirements. This is particularly valuable for contact center operators whose clients (healthcare, financial services, insurance) have their own compliance obligations.
