Answering machine detection, without compromise.
Ultra-fast, template-based AMD that transforms interviewer productivity — while staying compliant and imperceptible to respondents.
Cadence-based AMD is a “best guess” technology.
Typical false positive rates can be around 5% — live respondents incorrectly classified as answering machines. In regulated markets, that’s not just inefficient. It can be risky.
To stay compliant, predictive diallers often have to:
- Reduce overdial rates
- Limit algorithm efficiency
- Accept lower agent productivity
Historically, predictive dialling and AMD didn’t combine well. FastAMD changes that.
How answering machines consume interviewer time
Waiting time
Time spent waiting to detect an answer.
Connected time
Listening to recorded messages.
Wrap time
Post-call tasks and dispositioning.
Detection in 0.4 seconds. Yes, 0.4 seconds.
Template-based detection
A library of digital templates, derived from voicemail introductions across major PSTN and mobile carriers — including call screening messages — is matched against the first fractions of a second of audio in real time.
Microsecond processing
Matching happens in microseconds, with an average detection time of approximately 0.4 seconds from call start.
Imperceptible to respondents
No noticeable lag or “dead air” to alert live respondents to autodialling — reducing hostility and drop risk.
Not a probability guess. Near-absolute certainty.
FastAMD’s template-matching architecture results in an effectively negligible false positive rate — approximately 2–30 in a billion.
- Live respondents are not misclassified
- Silent call risk is dramatically reduced
- Predictive dialling can operate safely at higher efficiency
In regulated environments, this difference is critical.
FastAMD delivers measurable operational gains.
Agents spent significantly more time actively speaking with respondents.
A greater proportion of agent time is spent engaging with live respondents.
Agents handled substantially more live calls per interviewer hour.
Completed surveys per interviewer hour increased dramatically.
Campaigns would have run over 40% longer without FastAMD handling answering machines.
Overall productive live engagement time increased by nearly half through combined efficiency gains.
Performance and compliance, aligned.
Designed for predictive dialling
FastAMD was built to work with predictive algorithms — not against them. When false positives are effectively eliminated:
- Compliance thresholds remain protected
- Abandon rates stay controlled
- Dialler pacing can optimise safely
Enterprise-ready infrastructure
High-speed detection meets enterprise-grade hosting. FastAMD runs within:
- Secure AWS private cloud environments
- Region-specific deployments
- Managed SIP infrastructure
Higher talk time, without increased abandon risk.
By removing answering machines before they reach agents, FastAMD:
Reduces wasted interviewer capacity
Allows safe increases in overdial rates
Improves cost per complete
Shortens fieldwork timelines
It doesn’t just filter calls — it restructures efficiency.
Turn answering machines from a productivity drain into a competitive advantage.
