What is IAMD?

Answering Machine Detection with AI

Think of AMD as a gatekeeper that only lets real people through — that’s exactly how IAMD (Intelligent Answering Machine Detection) works. It analyzes the audio of every call in real time and decides in under 100ms whether there’s a human or a voicemail on the other end. If it’s a voicemail: hang up or leave a pre-recorded message. If it’s human: connect the agent instantly.

The 4 factors IAMD analyzes in every call
01
Initial Greeting Duration

Voicemails have a uniform, predictable greeting in length and cadence. A human response is more variable, hesitant, and natural.

02
Silence & Pause Analysis

Automated messages have structured pauses before playing the recording tone. IAMD detects these patterns instantly.

03
DTMF Tones & Acoustic Signals

Voicemail systems emit characteristic tones when activating recording mode. IAMD identifies these signatures with precision.

04
Voice Pattern Recognition

ML models analyze intonation, speed, and spectral frequencies to differentiate human voice from synthetic or recorded audio.

Detected: Voicemail / Machine

The call is disconnected automatically before the agent answers, or the system leaves a pre-recorded message. Zero agent time wasted.

Detected: Human

The call is connected immediately to the available agent. No waiting, no dead air. The customer hears the agent in the very first second.

New · Artificial Intelligence

From every call to actionable intelligence

IAMD tells you who answered. The AI layer tells you what happened in the conversation, why it was won or lost, and whether your script was followed — with the exact quote and second of the recording as evidence. Transcription runs 100% on-premise: your audio never leaves your infrastructure.

1
Record

Calls are recorded per route — mono, or stereo with agent and customer on separate channels.

2
Transcribe

On-premise speech-to-text with timestamps and speaker separation. No external cloud.

3
Analyze

Generative AI writes an executive summary and decides if the campaign objective was met: Yes / No.

4
Level 2 Insights

Agent score, customer sentiment, loss reason, objections and topic for every call.

5
Audit

Each item of your sales script is checked: Met / Not met, with exact quote and second.

6
Deliver

Dashboards, PDF reports, client portal and REST API — minutes after the call ends.

AI Profiles

Your criteria, in plain language

Each campaign defines what success means. Write it once — the AI applies it strictly and consistently to every call.

  • Context — who the auditor is, what the campaign sells and what to look for.
  • Resolution criteria — the exact rule for a Yes (e.g. “the customer accepted the contract”).
  • Level 2 categories — your own list of loss reasons and objections (up to 20).
  • Minimum duration and trunk assignment — analyze only the calls that matter, per client or trunk.
Softswitch Class 4 / 5

The brain behind every VoIP call

A Softswitch is more than routing — it’s the central intelligence that controls every traffic decision: how, when, at what cost, and with which codec.

Advanced Routing & LCR

Least-cost routing (LCR), priority, ANI prefix, and automatic real-time failover. Multiple routing policies configurable per client.

Real-Time Billing

Second-by-second billing while the call is active. Multi-currency support, balance alerts per client, and automatic cutoff at limit.

Native Transcoding

Built-in codec conversion: G.711 A/U, G.729, Opus and AMR. Interconnect networks with different codecs without external hardware or quality loss.

Active Calls Monitor

Real-time dashboard with active calls, channels per trunk, ASR, ACD and PDD per operator. Automatic alerts on traffic anomalies.

SIP Traffic Balancer

Load distribution across SIP servers with automatic failure detection and traffic redistribution without service interruption.

Exportable CDR Reports

Detailed record of every call with Q.850 cause, duration, cost, trunk and ANI. Exportable to CSV/Excel directly from the panel.

ANI Random / Prefix Magic

Dialing prefix management, random ANI rotation and heading manipulation to optimize contact rates on outbound campaigns.

Integrated SIP Tracer

Real-time capture and analysis of SIP messages. Diagnose registration, authentication and signaling issues without external tools.

Multi-Client Portal

Segmented access per client with their own panel: balance, CDR, active trunks and statistics. Each client sees only their own data.

CCA Module

Automatic Access Charges (CCA/PISA) per destination. Applied and calculated directly inside the billing engine.

Portability API

Real-time number portability query integrated into the routing engine. Automatic updates of NPV/NPC databases from the regulator.

Balance Alerts per Client

Automatic email/SMS notifications when balance, consumption or channel thresholds are reached. Configurable per client or trunk.

New · SMS

Voice, AI and now SMS — in the same platform

Connect your own SMS carriers over SMPP and sell SMS to your clients with the same accounts, tariffs, balance and portal you already use for voice. Your clients send from their systems with a simple API — and only pay for messages that are actually delivered.

Your Own SMPP Carriers

Connect any SMS provider over SMPP 3.4. Automatic reconnection and keep-alive, live link status in the panel and changes applied in seconds — no restarts.

Smart SMS Routing

Longest-prefix routes with priority and automatic failover to a backup carrier, number-length rules and prefix manipulation per route.

Charged Only When Delivered Fair

The cost is reserved from the client’s balance when sending and charged only when the carrier confirms delivery. Failed or unconfirmed messages are released automatically.

SMS Rates in Your Tariffs

SMS prices by prefix live in the same tariff as voice — one tariff per client for both services. CSV import and export, shared balance and credit limit.

Simple, Secure Client API

REST/JSON with a per-client token, plus a simple GET for legacy platforms. Requests are accepted only from the client’s authorized trunk IPs — a stolen token is useless.

Every Character Arrives

@, accents, ñ, € and emojis delivered correctly: GSM, Latin-1 or Unicode chosen per carrier, long messages split and rejoined on the phone without breaking a character.

Carrier-Friendly Throughput

Per-carrier sending speed and window: bulk traffic is queued and sent at the pace each carrier accepts, with automatic retry when the carrier asks to slow down.

Full Visibility

SMS history with delivery status and the exact failure reason (unknown number, no route…), CSV export, a dashboard indicator — and a client portal with history, API docs and a test window.

IAMD Module

Intelligent voicemail detection

IAMD goes beyond traditional AMD. Being integrated into the Softswitch, it makes decisions at the call core without adding latency or depending on external systems.

Native AMD in the Core

No external libraries, no added latency. Detection runs inside the SIP engine of the Softswitch with direct access to the RTP audio stream.

Per-Operator ML Model

Each carrier has its own detection model trained with real audio from your operation. Accuracy improves with every processed call.

Decision in <100ms

The time between audio start and the Human/Machine verdict is under 100ms. The agent connects before the customer notices any silence.

Auto-Action on Voicemail

When voicemail is confirmed: automatic disconnect or playback of a customizable pre-recorded message. Configurable per campaign or trunk.

Q.850 + ANI Reputation

Q.850 cause analysis per call and dynamic reputation scoring per ANI number. Detects fraud, misrouting and invalid numbers.

Auto Database Cleanup

Numbers with recurring invalid Q.850 causes are automatically flagged and removed from active dialing lists.

Early Media IAMD

Detects voicemail or IVR even before the call is answered (183 early media) and cancels it — that minute is never billed. Ringback is never cut.

Training with Your Traffic

Supervisors correct results from the CDR, the model is retrained and deployed without downtime. The more you use it, the more accurate it gets.

Feeds the AI Layer

Machines are detected and released first, so transcription and AI analysis focus on real human conversations — AI resources are spent where they matter.

Call Flow

How does Apolo Softswitch IAMD + IA + SMS work?

From the incoming call to the final destination, every decision happens in milliseconds inside a single unified engine.

1
Incoming Call

SIP traffic arrives from the client or provider via authenticated trunk.

2
IAMD Detection

Analyzes audio: human or voicemail? Decides in <100ms and acts instantly.

3
Routing Engine

Selects the best route by LCR, priority and ANI. Automatic failover if route fails.

4
Live Billing

The call is billed second by second. Automatic cutoff when limit is reached.

5
CDR & Report

When finished, the CDR is recorded with Q.850 cause, cost and quality metrics.

6
AI Analysis

Human calls are transcribed, analyzed, scored and audited automatically.

Transparent transcoding throughout the chain

If the client originates in G.729 and the destination requires G.711, the transcoding engine (G.711 A/U · G.729 · Opus · AMR) converts the codec automatically in step 3, without affecting IAMD detection latency or call quality.

Operational Impact

What IAMD changes in your operation

Measurable results from the first days of operation with outbound campaigns.
