VitalPBX FAQ.
What is VitalPBX?
VitalPBX is a business phone system (PBX) built on Linux and Asterisk. You install it on your own server, a virtual machine or a cloud VPS, then manage extensions, IVRs, queues, trunks, call center tools, WebRTC and mobile clients from one web interface. VitalPBX sells software licenses; you choose where it runs.
Is there a free version of VitalPBX?
Yes. The Community plan is free. It includes 12 extensions, unlimited simultaneous calls, the full feature set, 2 VitXi WebRTC clients, provisioning for up to 20 devices and forum support. Move to a commercial plan when you need more extensions, the Sonata Call Center Suite or ticket support.
Do I pay per user or per extension?
No. The Enterprise, Call Center and Multi-Tenant plans include unlimited extensions and unlimited simultaneous calls for one flat license, billed monthly, yearly or as a one-time purchase. Adding extensions never raises your license price. VitalPBX One is priced by the number of extensions you need.
Can one VitalPBX server host many companies?
Yes. The Multi-Tenant plan runs up to 100 tenants on one server. Each tenant gets its own extensions, routes, IVRs and settings, fully isolated from the others. It costs $250/month, $2,500/year or $10,000 one time, with no per-tenant fee.
Does VitalPBX include call center software?
Yes. The Sonata Call Center Suite adds Sonata Switchboard (live operator console), Sonata Stats (real-time and historical queue reports), Sonata Dialer (outbound campaigns), Sonata Billing (call rating and cost control) and Sonata Recordings (search and playback). The Call Center and Multi-Tenant plans include the full suite.
How does VitalPBX compare with 3CX and FreePBX?
VitalPBX puts a modern web interface, multi-tenant hosting, the Sonata Call Center Suite and AI tools in one product. Unlike 3CX, which licenses by simultaneous calls, VitalPBX commercial plans use a flat license with unlimited extensions. Unlike a bare FreePBX install, call center, WebRTC and mobile clients come from one vendor with one support channel. You run it on your own server, so you keep control of your data.
How do I install VitalPBX?
Download the VitalPBX 4.5 ISO (Debian 12) and install it on a physical server, run it on a virtual machine, or deploy it on a cloud VPS or marketplace image. A VPS install takes about 5 minutes.
