AMD Compliance: Answering Machine Detection Rules

Under TCPA, pre-recorded messages (including voicemails left by predictive or power dialers) must: (1) state the name of the company making the call at the beginning of the message; (2) provide a toll-free number that the called party can call to be placed on the company's DNC list; and (3) not contain obscene or harassing language. These requirements apply whether the voicemail was intentionally left or was the result of incorrect AMD classification.

The FTC's TSR caps the abandoned call rate at 3% of all calls answered by a live person per campaign. If AMD incorrectly classifies a live answer as a voicemail (a 'live answer false positive'), the call is effectively abandoned — the consumer picks up and hears nothing, or is played a pre-recorded message without agent transfer. High false-positive AMD rates directly cause abandoned call rate violations. Klozer.io's AMD achieves 95%+ accuracy, keeping false-positive rates well below the threshold where abandoned call violations become likely.

When a predictive dialer connects a call and no agent is available within 2 seconds of the consumer saying 'hello,' that call is considered abandoned. The FTC requires: an abandoned call rate of ≤3% (measured per campaign, per 30-day period); a recorded message must play identifying the caller and providing a callback number (and DNC opt-out option) when a call is abandoned; and agents must be available within 2 seconds of a consumer answering. Exceeding 3% abandoned rate is a TSR violation — up to $51,744 per violation.
