Your Agents Talk to Humans. Not Voicemails.
VICIdial's built-in AMD hasn't been meaningfully updated in over a decade. Our neural network replaces it entirely — trained on millions of real call recordings, delivering 98.3% accuracy with sub-200ms decisions. Your agents connect with live humans, not dead air.
The Problem: VICIdial's AMD Is Destroying Your Productivity
VICIdial's native answering machine detection relies on silence-based heuristics that were designed for landline-era voicemail greetings. Modern cell phone voicemails, carrier-injected messages, and VoIP systems produce audio patterns that consistently fool these outdated algorithms. The result is a false positive rate that routinely exceeds 30% — meaning nearly a third of your "answering machine" dispositions are actually live humans who were hung up on.
The financial impact is staggering. Every false AMD detection is a wasted dial, a burned lead, and a missed revenue opportunity. For a 50-seat center running predictive campaigns, inaccurate AMD easily costs $15,000–$30,000 per month in lost conversions, wasted carrier minutes, and inflated lead costs. Agents sit idle waiting for connects while the dialer hangs up on the very people they should be talking to.
The cascade effects are worse. Because your dial ratio has to compensate for all those false positives, you burn through lists faster, hit DNC triggers more often, and generate more carrier complaints. Many centers simply disable AMD entirely and accept the productivity hit of agents listening to voicemail greetings — trading one problem for another.
From Audio to Decision in Under 200ms
Audio Capture
The moment a call connects, ViciStack captures the first audio frames from the Asterisk channel and streams them to our classification engine in real-time.
Neural Classification
Our model, trained on millions of call recordings across dozens of industries, analyzes vocal patterns, cadence, and spectral features to distinguish humans from machines.
Routing Decision
Within 200ms, the call is routed: live humans go straight to your agents, answering machines are handled according to your campaign rules (hangup, leave voicemail, or retry).
Continuous Learning
Every classification feeds back into the model. Agent dispositions and call outcomes refine accuracy over time, adapting to new voicemail greetings and carrier behaviors.
