It comes in a 1U rack-mountable appliance equipped with high grade enterprise server components, including a Quad-Core CPU and up to 32GB RAM.
The 120 GB SSD (minimum) is more than ample to maintain your IP PBX functions.

With this much power, it easily handles up to 600 concurrent calls and register up to 3000 Extensions.
VitalPBX software is the Open Source version of the top-of-the-shelf Xorcom CompletePBX, which itself is based on Asterisk, an open source Unified Communications software.
When you purchase a VitalPBX appliance, you don’t pay per concurrent call or per extension!
There is no required maintenance, per user fees, or upgrade insurance to purchase.
Wavesat does recommend the purchase of a support contract to help you with your initial installation and setup of your new VitalPBX appliance, but our support option is tailored to fit your budget and your level of expertise.
The VitalPBX Enterprise IP-PBX Appliance features the latest version of the software, which is usually based on a 64bit version OS preloaded, which gives you everything you need for Unified Communications right out of the box.
