Today marks the one-week anniversary of Debian "trixie" 13.5 bringing critical security patches and some minor stability updates to this new operating system. It also addresses a major Linux kernel privilege escalation flaw (CVE-2026-46333) affecting default installs of Debian 13 as well as critical kernel patches. Debian 13 "trixie" will be supported for 5 years with three years of full, standard support and two years of Long Term Support (LTS).
With this new Debian 13.5 release, it seemed only fitting to also introduce the latest and greatest Incredible PBX ever. So we’re pleased to announce the immediate availability of Incredible PBX 2026 featuring Debian 13, FreePBX® 17, and your choice of Asterisk® 22 or 23. You won’t find a comparable release from Sangoma because they are at least many months away from supporting Debian 13. Incredible PBX 2026 brings Asterisk deployments into operating system equivalence with FusionPBX and FS PBX, two of our other favorite VoIP platforms. And it provides a gentle reminder to Sangoma that official security updates for Debian 12 conclude in less than three weeks. And yet Debian 12 remains Sangoma’s exclusive support platform for FreePBX 17. One cannot help wondering how a company that owns both Asterisk and FreePBX can find itself a full version out of compliance with both its operating system of choice as well as its own flagship product, Asterisk 23. But here we are. So, we hope you enjoy Incredible PBX while the Asterisk platform continues to wither on the vine.
Getting Started with Incredible PBX 2026
To begin your Incredible PBX 2026 adventure, you first will need a Debian 13 stand-alone platform or virtual private server with at least 2GB of RAM and a 20+ GB storage device. You can download the Debian 13 net install ISO from here. Burn it to a USB stick and then boot your machine from the USB drive and follow your nose. Install the base Debian 13 platform with the SSH and System Utilities options only. Login to your new server as root and issue the following commands to begin the Incredible PBX 2026 installation:
wget https://filedn.com/lBgbGypMOdDm8PWOoOiBR7j/IncrediblePBX2026/IncrediblePBX2026.sh chmod +x IncrediblePBX2026.sh ./IncrediblePBX2026.sh
Have a cup of coffee and return when the installer prompts you to create a default admin password for FreePBX GUI access. Immediately thereafter, you’ll be prompted to set up the default Postfix email platform. Simply tab to the confirmation option on the three setup screens to complete the Postfix setup procedure. Because most internet service providers block sending emails from a downstream server, you will also need to run the enable-gmail-smarthost-with-postfix script in the /root directory using a Gmail app password to actually activate Postfix. After a bit more whirring, you’ll be prompted to reboot your machine to complete the Incredible PBX 2026 install. You now can create your extensions, trunks, and outbound and inbound call routes, and your deployment will be complete.
