📞 PBX Features
Everything a traditional PBX does — plus an army of AI agents.
Core PBX Features
Extensions & Endpoints
Unlimited SIP extensions. Connect desk phones, softphones, mobile apps, and WebRTC browsers. Any device, anywhere.
Ring Groups
Route calls to groups of extensions simultaneously, sequentially, or in a hunt pattern. Never miss a call.
IVR / Auto Attendant
Multi-level interactive voice menus. Fully customisable with your own recordings or AI-generated prompts.
Call Queues
Professional call queuing with hold music, position announcements, estimated wait times, and overflow routing.
Call Transfer
Attended and blind transfers. Transfer between extensions, to external numbers, or to AI agents mid-call.
Announcements
Play custom announcements before routing. Business hours, holiday messages, special promotions.
Time-Based Routing
Route calls differently based on business hours, holidays, and time zones. After-hours goes to voicemail or AI.
Call Recording
Automatic recording of all calls. Stored locally on your hardware. No cloud storage fees.
Voicemail
Individual voicemail boxes per extension. Voicemail-to-email delivery. Visual voicemail in the portal.
SIP Trunking
Connect any SIP trunk provider. Bring your own numbers. Multiple trunks for redundancy.
CDR & Analytics
Complete call detail records. Real-time dashboards showing call volume, duration, answer rates, and peak hours.
VPN Built In
WireGuard + OpenVPN server included. Remote workers connect securely without exposing your PBX to the internet.
AI-Powered Features — What Traditional PBX Can't Do
AI Voice Agents
Deploy an army of AI receptionists, sales agents, and support bots. Each extension gets its own personality, voice, and instructions.
17 Languages
AI agents speak 17 languages natively. Automatic detection — caller speaks Spanish, Sarah responds in Spanish. Mid-call switching.
Voice Cloning
Clone any voice from a short audio sample. Your CEO's voice as the after-hours greeting. Your best salesperson — available 24/7.
Live Appointment Booking
AI agents book appointments directly into Google Calendar during the call. No human intervention. No double-booking.
Caller Memory
Sarah remembers every caller across sessions. "Welcome back, John. Last time you asked about the enterprise plan."
Transcription & Translation
Every call transcribed in real-time. Automatic translation to any language. Transcript + translation emailed instantly.
AI-to-Human Handoff
When the caller needs a human, Sarah does an attended transfer — briefing the agent before connecting. No cold transfers.
Emotion Analytics
Real-time sentiment analysis on every call. Know when callers are frustrated, happy, or confused. Dashboard with trends.
Outbound AI Dialling
Auto dialer connects outbound calls to AI agents. Reminders, follow-ups, surveys, and sales calls — all automated.
WebRTC Widget
Embed a call button on any website. Visitors click to talk to Sarah from their browser. No app, no phone number needed.
Unified Inbox
All channels in one inbox — calls, WhatsApp, Telegram, SMS, email, LinkedIn, web chat. One place. One view.
Email Marketing
Built-in bulk email marketing platform. Campaign management, templates, analytics. No Mailchimp needed.
