PBX Features
One Platform for Everything
Manage your entire business communications from a single dashboard.
Cloud PBX
Full-featured phone system with extensions, ring groups, IVR menus, call queues, voicemail, conference bridges, and time-based routing. No hardware required.
Built-in CRM
Manage contacts, companies, deals, and pipelines. Incoming calls automatically show caller info, and every interaction is logged to the contact timeline.
Web Phone
Make and receive calls directly from your browser using WebRTC. Built into the dashboard — no desktop app, no plugins, no hardware needed.
Call Recording
Record inbound and outbound calls for training, compliance, or quality assurance. Stream recordings in your browser or download them as audio files.
Workflow Automation
Automate repetitive tasks with trigger-based rules. Missed call? Automatically create a follow-up task, send an SMS, or notify your team.
AI Voice Agents
AI receptionist that answers inbound calls, asks your intake questions, captures lead details, and transfers to a human when configured. Available on the Enterprise plan.
An AI Receptionist That Knows Your Business
Native to your call routing. Ground it on your articles, PDFs, and FAQs in minutes. It answers, qualifies leads, and warm-transfers to your team when it's time to close.
Built into the routing
No plugins, no stitching. The agent is part of your dialplan, just like an extension or queue.
Trained on your knowledge
Upload articles, PDFs, and FAQs. The agent answers from your content — not from the open internet.
Smart hand-off to humans
When the conversation needs a person, the agent warm-transfers in real time.
Per-minute usage
Pay only for the minutes the agent is on a call. No flat AI subscription.

What Our Customers Say
Businesses rely on LeanPBX every day.
"We switched from a traditional PBX and had everything running the same afternoon. The web phone means our remote team doesn't need any extra software — they just log in and start taking calls."
David Reynolds
Operations Manager, Professional Services
"The built-in CRM is what sold us. When a customer calls, their info pops up instantly. We can add notes, set follow-up tasks, and track deals — all without leaving the phone system."
Sarah Mitchell
Sales Director, Real Estate Agency
"I was paying three times as much with our previous provider and getting half the features. The prepaid billing is refreshing — I know exactly what I'm spending and there are never any surprise charges."
James Thornton
Owner, IT Consulting Firm
Frequently Asked Questions
How do AI Voice Agents work?
AI Voice Agents answer inbound calls, follow your custom intake script, capture caller details, and transfer urgent callers to a human when configured. The agent answers using the business knowledge and rules you provide. Available on the Enterprise plan.
Do I need any special hardware?
No. LeanPBX is fully cloud-based. You can use our built-in web phone, any SIP-compatible desk phone, or a softphone app on your mobile device.
Is there a long-term contract?
No. All plans are month-to-month with no long-term commitments. You can upgrade, downgrade, or cancel at any time.
Can I keep my existing phone numbers?
Yes. We support number porting so you can transfer your existing phone numbers to LeanPBX without any downtime.
What happens if my balance runs out?
You can set up low balance alerts and auto top-up to avoid running out. If your monthly billing fails, the system retries for three days. Once you add funds, service is restored automatically.
How do I get help if I need it?
Browse our Help Center for step-by-step guides, open a support ticket from your dashboard, or email us directly. Contextual help is also available on every page inside the dashboard.
