Compliance starts at the carrier.
Your compliance program is only as strong as the carrier infrastructure underneath it. SIPNEX provides the carrier-layer foundation — FCC licensing, STIR/SHAKEN attestation, RMD registration, and the tooling that makes your TCPA compliance program defensible.
Compliance in outbound voice has two layers — the operator layer (consent capture, DNC scrubbing, calling-hour enforcement, abandonment rate controls) and the carrier layer (FCC licensing, STIR/SHAKEN signing, robocall mitigation filing, traceback cooperation). Most operators focus on the first layer and assume the second is handled. It often is not. A reseller without its own certificate cannot sign calls at A-level. A platform without an active RMD filing is vulnerable to downstream blocking. A carrier without an FCC license cannot legally provide the service at all.
SIPNEX solves the carrier layer completely. We hold our own FCC authorization, file our own Form 499 as a USF contributor, maintain our own STIR/SHAKEN SP-KI certificate, and register our own filing in the Robocall Mitigation Database with a complete STIR/SHAKEN implementation. That means every call originating on SIPNEX leaves our switches signed at A-level, every number on your account is attestation-eligible, and every traceback request we receive is handled in full cooperation with the Industry Traceback Group under TRACED Act obligations.
The pages below walk through each component of the carrier-layer program. Read STIR/SHAKEN to understand attestation mechanics. Read TCPA to see what the carrier provides and what the operator owns. Read Robocall Mitigation to understand the RMD and what your carrier's filing status means for your traffic. Read FCC Licensing to see how to verify any carrier's credentials independently. If you are evaluating carriers, everything on this page is publicly verifiable — you do not have to take our word for it.
STIR/SHAKEN
Cryptographic caller ID verification. SIPNEX holds its own SP-KI certificate and signs every originating call at A-level. How attestation works, why it matters, and what it means for your answer rate.
TCPA Compliance
The Telephone Consumer Protection Act governs consent, DNC, calling hours, and auto-dialer usage. What carriers provide and what operators own in the compliance stack.
Robocall Mitigation
FCC Robocall Mitigation Database registration, traceback cooperation, and traffic monitoring. Why your carrier's RMD status determines whether your calls reach the network.
FCC Licensing
SIPNEX is an FCC-licensed telecommunications carrier with its own Form 499 filing. What carrier licensing means, why it matters, and how to verify your provider's status.
Verifiable credentials. Not marketing claims.
Every credential listed here is independently verifiable through public FCC databases. Search our FCC license on the Universal Licensing System. Check our RMD filing at the FCC portal. Verify our STIR/SHAKEN certificate through the STI-GA. We publish these because we hold them. Carriers that do not publish them usually do not hold them.
