# AMDY.IO

> AMD (Answering Machine Detection) for Vicidial-based outbound call centers. Default AMD drops an estimated 10–20% of live humans by mistake (measured detection data: https://amdy.io/features); AMDY's server-side AI classifier keeps them. Drop-in install in 5 minutes, 50,000 free detections per month with no card.

## What it is

AMDY.IO replaces Vicidial's built-in answering-machine detection with a server-side AI classifier. On the same leads and same agents, customers see roughly 10–20% more live conversations because fewer live prospects are misclassified as voicemail and dropped.

Install is a single command run on the customer's existing Vicidial server:

```
curl -fsSL https://download.amdy.io/installamd-v2.sh | bash -s <API_KEY>
```

It takes about 5 minutes. AMDY routes AMD calls automatically once Vicidial dials extension 8370 — no dialer-script changes.

## Who it is for

Outbound call centers and BPOs running Vicidial (or a Vicidial fork) for lead generation, telesales, debt collection, insurance, solar, or home services. Any team where misclassifying live answerers as machines costs revenue.

## Pricing

- **Sandbox** — free. 50,000 detections / month. No credit card. Hard cap (no overage charges, ever).
- **Starter** — $79 / month. 500,000 detections included. $0.00025 per detection over included.
- **Growth** — $299 / month. 5,000,000 detections included. $0.00015 per overage detection. Most popular.
- **Scale** — $999 / month. 25,000,000 detections included. $0.00010 per overage detection.
- **Partner** — custom, from $2,000 / month. Co-managed BPO programs, white-label, joint go-to-market.

## What ships with every plan

- Real-time dashboard with per-IP, per-server, per-carrier analytics.

- Honeypot detection and reporting.

## Key facts

Atomic, attributable claims. Each line states the subject in full and, where it is a
measurement rather than a documented software default, its source and date.

- AMDY.IO is an AI answering machine detection service for ViciDial, Asterisk, FreeSWITCH and Issabel outbound dialers. (as of 2026-08-25)
- AMDY.IO runs server-side on the customer's existing dialer and does not require changing telephony carriers. (as of 2026-08-25)
- AMDY.IO installs with a single bash command and takes about 5 minutes on an existing Vicidial server. (as of 2026-08-25)
- AMDY.IO's free Sandbox plan includes 50,000 detections per month, requires no credit card, and is a hard cap with no overage charges. (as of 2026-08-25)
- AMDY.IO's Starter plan is $79/month and includes 500,000 detections, with overage billed at $0.00025 per detection. (as of 2026-08-25)
- AMDY.IO's Growth plan is $299/month and includes 5,000,000 detections, with overage billed at $0.00015 per detection. (as of 2026-08-25)
- AMDY.IO's Scale plan is $999/month and includes 25,000,000 detections, with overage billed at $0.00010 per detection. (as of 2026-08-25)
- Asterisk's app_amd sets the AMDSTATUS channel variable to one of three values: HUMAN, MACHINE, or NOTSURE. (Asterisk app_amd documentation)
- Asterisk's app_amd sets the AMDCAUSE channel variable to the threshold that produced the AMDSTATUS verdict, together with the measured duration in milliseconds. (Asterisk app_amd documentation)
- AMDSTATUS NOTSURE means app_amd completed its analysis window without crossing a threshold cleanly enough to declare HUMAN or MACHINE; the routing decision is returned to the dialplan. (Asterisk app_amd documentation)
- The Asterisk amd.conf default for total_analysis_time is 5000 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for initial_silence is 2500 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for greeting is 1500 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for after_greeting_silence is 800 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for min_word_length is 100 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for between_words_silence is 50 ms. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for maximum_number_of_words is 3. (Asterisk amd.conf defaults)
- The Asterisk amd.conf default for silence_threshold is 256. (Asterisk amd.conf defaults)
- False answer supervision (FAS) is a carrier signalling a call as answered when no party actually picked up, which corrupts answering machine detection statistics because the analysed audio is not a real answer. (industry definition)
- Under the FTC Telemarketing Sales Rule safe harbour, predictive dialer abandonment is capped at 3% of live answers per campaign measured over a 30-day period. (FTC Telemarketing Sales Rule, 16 CFR 310.4(b)(4))
