An enterprise Class 4/5 Softswitch with intelligent voicemail detection built into the core. Route, bill, transcode, and decide in milliseconds whether there’s a human or a machine on the other end — all in one platform.
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.
Voicemails have a uniform, predictable greeting in length and cadence. A human response is more variable, hesitant, and natural.
Automated messages have structured pauses before playing the recording tone. IAMD detects these patterns instantly.
Voicemail systems emit characteristic tones when activating recording mode. IAMD identifies these signatures with precision.
ML models analyze intonation, speed, and spectral frequencies to differentiate human voice from synthetic or recorded audio.
The call is disconnected automatically before the agent answers, or the system leaves a pre-recorded message. Zero agent time wasted.
The call is connected immediately to the available agent. No waiting, no dead air. The customer hears the agent in the very first second.
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.
Least-cost routing (LCR), priority, ANI prefix, and automatic real-time failover. Multiple routing policies configurable per client.
Second-by-second billing while the call is active. Multi-currency support, balance alerts per client, and automatic cutoff at limit.
Built-in codec conversion: G.711 A/U, G.729, Opus and AMR. Interconnect networks with different codecs without external hardware or quality loss.
Real-time dashboard with active calls, channels per trunk, ASR, ACD and PDD per operator. Automatic alerts on traffic anomalies.
Load distribution across SIP servers with automatic failure detection and traffic redistribution without service interruption.
Detailed record of every call with Q.850 cause, duration, cost, trunk and ANI. Exportable to CSV/Excel directly from the panel.
Dialing prefix management, random ANI rotation and heading manipulation to optimize contact rates on outbound campaigns.
Real-time capture and analysis of SIP messages. Diagnose registration, authentication and signaling issues without external tools.
Segmented access per client with their own panel: balance, CDR, active trunks and statistics. Each client sees only their own data.
Automatic Access Charges (CCA/PISA) per destination. Applied and calculated directly inside the billing engine.
Real-time number portability query integrated into the routing engine. Automatic updates of NPV/NPC databases from the regulator.
Automatic email/SMS notifications when balance, consumption or channel thresholds are reached. Configurable per client or trunk.
Apolosoftswitch + IAMD is structured in 7 functional groups — 24 modules in production. Select any module to see exactly what it does.

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.
No external libraries, no added latency. Detection runs inside the SIP engine of the Softswitch with direct access to the RTP audio stream.
Each carrier has its own detection model trained with real audio from your operation. Accuracy improves with every processed call.
The time between audio start and the Human/Machine verdict is under 100ms. The agent connects before the customer notices any silence.
When voicemail is confirmed: automatic disconnect or playback of a customizable pre-recorded message. Configurable per campaign or trunk.
Q.850 cause analysis per call and dynamic reputation scoring per ANI number. Detects fraud, misrouting and invalid numbers.
Numbers with recurring invalid Q.850 causes are automatically flagged and removed from active dialing lists.
From the incoming call to the final destination, every decision happens in milliseconds inside a single unified engine.
SIP traffic arrives from the client or provider via authenticated trunk.
Analyzes audio: human or voicemail? Decides in <100ms and acts instantly.
Selects the best route by LCR, priority and ANI. Automatic failover if route fails.
The call is billed second by second. Automatic cutoff when limit is reached.
When finished, the CDR is recorded with Q.850 cause, cost and quality metrics.
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.
Measurable results from the first days of operation with outbound campaigns.
Distinguishes voicemail from human with 97% accuracy using ML models trained on your traffic.
Dramatic reduction in agent time consumed on calls that end in voicemail.
More calls reach real people. More real conversations per agent hour.
Detection and action happen before the agent or customer perceives any silence.
Having Softswitch and AMD on the same platform eliminates latency, integration costs and single points of failure.
