Stock Asterisk AMD drops an estimated 10–20% of live humans as voicemail. Every one is a connect your agent never hears. Enter your operation below to see what those false positives cost per month, and the payback on AMDY’s $79 Starter plan. Every formula is shown.
Answered calls your AMD classifies each day.
Used for the labor-at-stake figure below.
Fully loaded cost per hour.
Default 15%, the midpoint of the estimated 10% to 20% live-human misclassification range stated on the AMDY homepage for stock Asterisk AMD.
liveCallsPerDay = 10,000 × 12.5% = 1,250 droppedPerDay = 1,250 × 15% = 188 valuePerLiveCall = $18/hr × (3 min ÷ 60) = $0.90 revenueLostMonth = 188 × 22 days × $0.90 = $3,713 droppedWithAmdy = 1,250 × 1% = 13 recoveredPerDay = 188 - 13 = 175 recoveredPerMonth = 175 × 22 days × $0.90 = $3,465 amdyCostMonth = Starter $79 (under 500K included) = $79 payback = $79 ÷ ($3,465 ÷ 30) = 0.7 days
Four inputs drive every output. The formulas, in order:
Hours of dialing per day does not multiply the loss, because the loss already scales with call volume. It sets the labor-at-stake figure: hours × agent cost × 22 days, so you can see the lost revenue as a share of what the dialing operation costs to run.
The default false-positive rate is 15%. The AMDY homepage states that the stock Asterisk AMD built into predictive dialers drops an estimated 10% to 20% of live humans as voicemail, and 15% is the midpoint of that estimate. Stock AMD runs about 70% to 85% accurate overall. Our live measured platform data is on the features page.
The 12.5% live-call share comes from The State of AMD 2026, a review of 2.3 billion answered outbound calls across the AMDY network over 30 days: 12.5% of answered calls were a live human, 73.2% were a machine, and 14.2% were carrier false answers. The 99% accuracy figure for AMDY is measured across those same ~2.3 billion monthly answered calls, with detection starting in 1/8 of a second.
The $79 Starter price, the 500,000 included detections, and the $0.00025 overage rate come from the same pricing config that powers our pricing page. If your cost is agent time burned on machines instead of dropped live calls, the companion dialer ROI calculator models that side.
Estimate only, not a guarantee. Accuracy figures are typical results measured across the AMDY network, and your numbers depend on your list, carrier, and campaign. See your real human-vs-machine split on 50,000 free Sandbox detections before you pay anything.
Sandbox is free: 50,000 detections a month, no card, hard cap. One-command Vicidial install in under 5 minutes.
When AMD misclassifies a live person as a machine, the dialer drops the call. The built-in Asterisk AMD that ships with predictive dialers drops an estimated 10-20% of live humans as voicemail, per the AMDY homepage estimate. Every one of those is a connect your agent never hears: paid dialing labor that should have become a conversation becomes a sub-ten-second hangup instead, and the drop never shows up in your abandoned-call reporting because it was logged as a machine.
The stock Asterisk AMD is a timing heuristic that guesses human vs machine from silence and greeting length. It runs about 70% to 85% accurate and drops an estimated 10% to 20% of live humans, the same estimate stated on the AMDY homepage. The midpoint of that estimate, 15%, is the default in this calculator. Live measured platform data is published at https://amdy.io/features.
Across 2.3 billion answered outbound calls on the AMDY network over 30 days, 12.5% were a live human, 73.2% were a machine (voicemail, IVR, recording), and 14.2% were carrier false answers where nobody picked up at all. This calculator uses the 12.5% figure as its live-call share. Your own mix varies by list, carrier, and campaign.
Plans bill monthly, not per server. Sandbox is free: 50,000 detections a month, no card, hard cap. Starter is $79/month with 500,000 detections included, then $0.00025 per detection over. Growth is $299/month with 5,000,000 included, and Scale is $999/month with 25,000,000 included. This calculator models the Starter plan.
AMDY classifies the acoustic signature of the answer at 99% accuracy, with detection starting in 1/8 of a second. Both figures are measured across the roughly 2.3 billion answered calls on the AMDY network each month. AMDY also flags carrier false answers (FAS) and honeypots that stock timing-based AMD cannot see.
Payback depends on your volume, agent cost, and current false-positive rate: enter your numbers above and the calculator shows the formula with your inputs. The homepage FAQ notes most operators cover the cost from the extra live conversations in the first month. Sandbox lets you verify on 50,000 free detections of real traffic before you pay, and the Vicidial install is one command that runs in under 5 minutes.
