We give you the infrastructure. You own the policy.

The Telephone Consumer Protection Act (47 U.S.C. § 227) is the federal law governing autodialed calls, prerecorded messages, and text messages to consumers. It establishes consent requirements (prior express consent for informational calls, prior express written consent for telemarketing), Do Not Call obligations, calling hour restrictions (8am–9pm recipient local time), and abandon rate limits (3% for predictive dialers). Penalties are $500 per negligent violation and $1,500 per willful violation with no cap.

SIPNEX provides carrier-layer infrastructure that supports your TCPA compliance program: A-level STIR/SHAKEN attestation (verified caller identity on every call), call recording infrastructure (for consent documentation and quality assurance), real-time CDR access (timestamps, durations, and dispositions for compliance auditing), and carrier-level traffic monitoring (anomaly detection for calling pattern issues). These are the tools. Your compliance policy determines how you use them.

Consent capture and storage (obtaining and documenting valid consent for every number you dial). DNC scrubbing (National Registry every 31 days, company-specific lists, state lists). Calling hour enforcement (8am–9pm in the recipient's local time zone, with state-specific restrictions). Abandon rate management (under 3% for predictive dialing, measured per campaign over 30 days). Campaign content compliance (required disclosures, opt-out instructions). Record keeping sufficient to defend against litigation.

No. They operate at completely different layers. STIR/SHAKEN verifies caller identity at the carrier level — it determines whether your call displays as verified or gets flagged as spam. TCPA is a consumer protection law governing consent, DNC, and calling practices. You can have perfect A-level attestation and still face massive TCPA liability if you call without consent. You need both: the right carrier for attestation and your own compliance program for everything else.

SIPNEX provides carrier-level call recording on all trunks. Recordings are linked to CDRs with timestamps. For two-party consent states (15 states require all parties to consent to recording), you must play a disclosure before recording — SIPNEX's recording infrastructure supports this workflow. We provide the recording capability. You configure the disclosure, manage consent, and comply with state-specific recording laws.

DNC scrubbing is the operator's responsibility. SIPNEX does not perform DNC scrubbing on your behalf — we do not have access to your lead lists and we cannot determine your consent status for individual numbers. We provide CDR data that supports compliance auditing (verifying that no calls were placed to DNC numbers), but the scrubbing itself must happen in your CRM or dialer before leads enter the hopper.

TCPA liability falls on the caller (the entity that placed the call), not the carrier. However, SIPNEX monitors for traffic patterns associated with illegal robocalling and may investigate accounts that generate unusual complaint volumes or calling patterns. Our Acceptable Use Policy prohibits illegal calling practices. We provide the infrastructure for compliant operations — abuse of that infrastructure violates the AUP and can result in service suspension.

After the Supreme Court's 2021 Facebook v. Duguid decision, VICIdial (which dials from uploaded lists, not random/sequential number generation) likely does not qualify as an ATDS under the federal TCPA. However, some state laws define ATDS more broadly (notably Florida), and the FCC's ongoing interpretive guidance continues to evolve. The safest approach: treat your dialer as an ATDS and obtain prior express written consent for all telemarketing calls. See our TCPA compliance checklist blog post for the full analysis.
