Asterisk Voice & AI
Open-source telephony you own, with AI answering in front of it.
Asterisk is the open-source engine behind a large share of the world's telephony. We run it as a managed platform with AI voice agents in front: you keep control of the call path and the data, without per-seat licensing dictating how you operate.
What Asterisk Voice & AI delivers
No per-seat ceiling
Scale lines and agents without a licence renegotiation every time the team grows.
Your data, your call path
Recordings, transcripts and routing logic stay in infrastructure you own and can audit.
Managed, not abandoned
Patching, security, trunk failover and capacity handled as a service — the part self-hosted voice usually gets wrong.

Why this matters
Functional value, value-stream value — and why it can't be ignored.
Builds, hosts and manages Asterisk — dial plans, trunks, recording, security and scaling — with AI voice agents and integrations layered on top.
The infrastructure layer of voice. It determines what every downstream stage can do, and whether call data is yours to analyse or locked inside a vendor platform.
Per-seat voice licensing punishes growth, and closed platforms keep your call data. Asterisk removes both constraints — provided it is engineered and maintained properly, which is where self-managed deployments usually fail.
One data layer · measured & owned
Every service creates data — captured, measured, owned.
Asterisk Voice & AI doesn’t just run — it generates signal. We land that data in one warehouse and turn it into live KPIs tied to a named owner, so performance is attributable and acted on, never trapped inside a single tool.

Apache Superset Platform-agnostic — we connect what you already use and add a warehouse only where it earns its place.
How we select technology
We choose technology last — for the outcomes it has to earn.
Never tech for its own sake. A tool joins the stack only where it measurably protects value, cuts cost or unlocks speed — fit to a designed system, owned where it counts, and measurable from day one. How we select technology →
Speed
Modern, edge-served stacks are sub-second. Slow surfaces cost conversion and SEO every single day.
Cost
Cut licence, hosting and per-task SaaS fees — pay for capability, not lock-in or idle enterprise tiers.
Security
Flat, edge architecture with almost nothing left to attack — fewer moving parts, smaller surface.
Ownership & no lock-in
Composable and self-hosted where it counts — you own the system, not rent someone else’s.
Measurability
Clean data and KPIs baked in — you cannot improve, automate or apply AI to what you cannot measure.
Fit to process
The right tool for a designed system — selected against process readiness, so it amplifies, not adds friction.
How we deliver · DMAIC
Every Asterisk Voice & AI engagement runs on DMAIC.
Define the goal and its value, measure the baseline, analyse the real constraint, improve with a proven build, then control the gains — so results are predictable, repeatable and defensible, not down to luck.
Agree the goal, value, budget & timescale up front.
Baseline the KPIs above — current state, not guesswork.
Diagnose the real constraint and the solution needed.
Build the chosen solution; prove the uplift.
Lock in the gains; monitor and sustain them.
