The one thing we’ve learned over the past decade is that everyone’s telecommunications needs are different. We began the Incredible PBX™ project by offering a script for PBX in a Flash™ that enhanced its functionality by adding three dozen applications for Asterisk® plus a rock-solid, preconfigured firewall. We expanded on that initial design by offering installers to support both Elastix® 4.0 and even the FreePBX® Distro and AsteriskNOW. But many asked for something more. Some wanted a turnkey install on inexpensive hardware so we now have a Raspberry Pi® 3 image that configures itself in under a minute. Others wanted and we provided an ISO image that could be loaded onto a USB thumb drive and used to install Incredible PBX on virtually any standalone hardware platform including the $200 Intel NUC. Then there were the enthusiasts that insisted upon virtual machines for virtually everything. So we built Incredible PBX images for Proxmox, and VirtualBox, and VMware. All of these builds could be set up about as quick as you can snap your fingers. Still others believed that all computing should be handled with Cloud-based servers. So we created a $10.50 solution for lifetime Cloud computing with CloudAtCost, a $5/month solution with Digital Ocean, and a $15/month rock-solid reliable PBX with RentPBX. Finally, there were operating system purists. Some preferred RedHat/CentOS/Scientific Linux while others swore by Debian or Ubuntu or Raspbian 8. So we added Incredible PBX builds for every conceivable operating system.

What remained consistent through all of these Incredible PBX iterations was our absolute commitment to providing a secure computing environment out of the box with a feature set unmatched in both the open source and commercial PBX communities. But, of course, there is always someone that doesn’t want features and prefers a secure platform on which to build their own servers. We’ve even accommodated that request with the Lean, Mean Edition of Incredible PBX.

So, today while we work on taxes, you can take a leisurely stroll through all of the available Incredible PBX links above and choose a platform that best meets your needs. Our other uncompromising feature is price. Incredible PBX is and always will be free with NoGotchas. If you’re still confused about choosing a favorite build, try our Decision Tree below. It’ll give you suggestions in less than a minute. Come join the party!
