TCPA-compliant outbound dialing — what your platform actually has to do

Calling windows, DNC enforcement, prior express written consent, state-level supplements, and the TCPA controls your dialer should provide without making you a legal expert.

The stakes

TCPA (Telephone Consumer Protection Act) violations carry statutory damages of $500 to $1,500 per call. Class action suits routinely settle for millions. Some of the largest contact center operators have paid 9-figure settlements for non-compliant outbound programs.

The threshold for violation is low: auto-dialing a cell phone without prior express written consent is a violation, even if the call was legitimate and the recipient doesn't complain. TCPA plaintiffs' law firms actively recruit recipients of calls that violate the rules.

Your contact center platform doesn't make you legally compliant by itself — you need policies, consent management, and audit trails. But a platform that doesn't enforce the core rules automatically is a platform that makes compliance failure almost inevitable.

The foundation of TCPA compliance: before you can auto-dial a cell phone with a marketing message, you need prior express written consent from the recipient.

"Written" includes:

  • Paper signature
  • Electronic signature (e-sign compliant)
  • Checkbox on a web form that explicitly states the consumer consents to auto-dialed calls
  • Recorded verbal consent in specific circumstances

"Express" means the consent language cannot be buried in a 10-page terms-of-service scroll. It must clearly state that the consumer is agreeing to receive auto-dialed calls from your company.

Your platform's job: integrate with your consent management system so the dialer won't dial a cell phone without a valid PEWC record on file.

Ask your vendor: "Can the dialer check a consent database per-call and suppress the call if PEWC is missing or expired?"

Calling window enforcement

Federal TCPA rules and most state rules restrict when you can make telemarketing calls. Federal baseline:

  • No calls before 8:00am or after 9:00pm in the recipient's local time zone

State supplements vary. Some states have tighter windows for specific call types. Some states restrict weekend calling entirely.

Your dialer must enforce time zones by the recipient's location (derived from phone number or address), not by the agent's location.

Ask your vendor: "Show me the calling window controls. How do they derive the recipient's time zone? What happens if an agent manually tries to place a call outside the window — is it blocked, warned, or logged?"

DNC list enforcement

Your dialer must suppress calls to:

  1. National Do Not Call Registry — federal list, updated daily
  2. State DNC lists where applicable
  3. Internal (company-specific) DNC list — customers who have asked you specifically to stop calling
  4. Wireless DNC enforcement — separate rules for cell phones

DNC list updates happen daily. A compliant dialer pulls updates daily and suppresses matches before dialing, not after.

Ask your vendor: "How frequently does the dialer refresh DNC lists? Is there an internal DNC list I can manage, and can agents flag calls to add recipients to it?"

Call abandonment rates

FTC's Telemarketing Sales Rule (adjacent to TCPA) limits predictive dialers to a 3% call abandonment rate, measured monthly, across all campaigns. A call is "abandoned" when the dialer connects before a live agent is ready and the customer hangs up.

Your dialer must:

  • Measure abandonment rate in real time
  • Auto-throttle dialing when the rate approaches 3%
  • Produce monthly abandonment reports for audit

Ask your vendor: "How is abandonment rate calculated? Can I see it in real time? Does the dialer auto-throttle to stay under 3%?"

Call identification

Every outbound call must:

  • Use a valid caller ID (not spoofed, not random)
  • Identify the caller's name and phone number within 15 seconds of the call connecting
  • Provide a clear way to opt out of future calls

Ask your vendor: "Can I require disclosure scripts to play at the top of every outbound call? Is that logged?"

Campaign-level audit trails

When a TCPA complaint lands, you need to reconstruct exactly what happened:

  • When was the number dialed?
  • What consent record was on file at dial time?
  • What was the call outcome (connected, abandoned, voicemail, answered by human)?
  • If the call was answered, what script played, what was said, was the recipient put on DNC afterward?

Without this audit trail, your legal team is flying blind.

Ask your vendor: "For a specific dialed number, can I retrieve the full call audit — consent state, calling window, disposition, recording — at any point in the future?"

Text messages (SMS) have their own rules

SMS campaigns are subject to TCPA equivalents. PEWC is required for marketing SMS. Recipients must be able to opt out via "STOP" or similar keyword. Carriers enforce carrier-level suppression independently.

Ask your vendor: "Does SMS opt-out processing happen automatically? How is it logged?"

The SingleComm outbound posture

SingleComm's outbound dialer covers the core TCPA controls:

  • Per-campaign calling window configuration with recipient-time-zone resolution
  • Real-time national + state + internal DNC list enforcement
  • PEWC integration hooks (import from CRM, suppress at dial time)
  • Predictive dial with real-time abandonment rate monitoring and auto-throttle below 3%
  • Carrier-safe SMS opt-out keyword processing
  • Complete per-call audit trail retained per your configuration
  • Disposition tracking that supports post-call DNC flagging

SingleComm is not a substitute for legal advice or a compliance program. The platform enforces the rules your team configures. Your compliance officer still owns the policies, the training, and the consent database.

What to do next

  1. Audit your current outbound program against the controls above.
  2. Identify gaps — typically missing PEWC integration or unclear DNC refresh cadence.
