New · Cloud PBX with AI

Your phone system. Spoken by your AI.

What sets it apart

Not just another phone system.

Three things no mainstream provider gives you together.

One server per customer

No shared multi-tenant bridge. Your PBX lives in a dedicated container. Exportable, snapshottable, migratable — your calls, your server.

AI-native, not "integrated"

FreeSWITCH ESL, Whisper.cpp STT and Piper TTS exposed as an MCP server. Your agent calls tools like originate_call or listen_stt directly.

Anti-fraud from day one

Per-tenant concurrent-channel caps, geographic outbound allow-lists, a daily spend ceiling with auto-suspend, plus APIBan and Fail2ban at the edge. One accidental international call won't wreck your month.

Features

Everything you expect from a PBX.

Plus everything you don't: your AI agent as just another extension.

Unlimited extensions

Standard SIP. Register any softphone (Linphone, Zoiper, Microsip) or desk phone (Yealink, Fanvil) with TR-069 auto-provisioning.

Built-in WebRTC

Call from the browser with mod_verto — nothing to install on the user's computer.

IVR · queues · groups

Design welcome menus, distribute calls and manage schedules from the FusionPBX UI, under your brand.

Recording + transcription

Record every call, Whisper.cpp transcribes it automatically, and your AI agent generates a summary sent to your CRM or inbox.

TLS + SRTP

End-to-end encrypted signalling and media, with an automatic Let's Encrypt certificate on your subdomain.

ES + EU + international numbers

Geographic and nomadic Spanish numbers plus international DIDs, with number portability included.

CDR + reports

Real-time detail on every call, exportable to CSV, with webhooks to your own systems.

API + webhooks

FusionPBX REST plus the Kawkav MCP. Integrate with your CRM, helpdesk, calendar or automation flows.

The difference

Your AI agent answers the phone.

Connect any MCP client to your PBX in one click. The agent gets nine tools to control calls: originate, answer, transfer, speak (TTS), listen (STT), record, bridge to a human, and hang up.

Inbound AI receptionist

Answers after hours, qualifies the caller and transfers to the right person.

Scripted outbound calls

Appointment confirmations, collections, surveys and win-back campaigns.

Post-call summary

Transcription plus action extraction, pushed straight into your CRM.

Live coach

Your agent listens and whispers suggestions to the human on a side channel.

Smart voicemail

Every message becomes text plus sentiment and priority, routed to the right person.

Any MCP client

Bring your own agent — it becomes a first-class participant on your phone tree.

Real use cases

Built for your sector.

Six scenarios where the PBX plus an AI agent pays for itself in the first month.

Healthcare · clinics

24/7 reception. The AI answers after hours, checks the calendar by API, confirms or reschedules, and texts a confirmation. In the morning the receptionist gets a summary.

Real estate · sales

Lead qualification. The AI answers, asks five qualifying questions and transfers only the valid leads — up to 3× more closings per agent.

Law firms

Smart voicemail. Every message becomes a transcription plus a triage label (urgent / normal / spam), routed to the right lawyer within 90 seconds.

E-commerce · support

Automated tier-1 support. The AI takes the order number, checks your API and gives status or tracking. Only complex cases escalate to a human.

Hospitality · reservations

Multichannel booking. The AI takes reservations, checks availability in your PMS or calendar and confirms by SMS, so the team looks after the guests in front of them.

Logistics · collections

Reminders and collections. The AI works the list each morning, states the balance, offers a payment link and logs promises; your team steps in only to negotiate.

Pricing

Simple. No surprises on the invoice.

A fixed subscription per PBX. Bring your own trunk for minutes, or buy them in blocks. Spend caps included.

Questions

The honest answers.

Is this really a dedicated PBX, or shared?

Dedicated. Your PBX runs in its own container — not a shared multi-tenant bridge. It's exportable, snapshottable and migratable at any time.

How does the AI agent connect?

Through an MCP server that exposes nine call-control tools. Any MCP client can originate, answer, transfer, speak, listen, record, bridge to a human and hang up.

How do you stop toll fraud?

Per-tenant channel caps, a geographic outbound allow-list, a daily spend ceiling with auto-suspend, and APIBan plus Fail2ban at the edge.

Where do the numbers come from?

Geographic and nomadic Spanish numbers plus international DIDs, with portability included. Bring your own trunk if you prefer.

How fast is provisioning?

Under 90 seconds after payment confirmation: a dedicated container, FreeSWITCH configured, FusionPBX ready, registered with the public edge — ready for your first softphone.
