VICIdial scratch install / Debian 12

VICIdial scratch install on Debian 12

One command installs stock VICIdial r4035 on Debian 12: Asterisk 22 built for Debian 12, PHP 8.3 from packages.sury.org (Debian 12 ships 8.2), MariaDB 10.11, Apache with mod_php, a firewall and, by default, a campaign with fronters and closers ready to log in. It took 3m 20s on a 4-core server.

Last tested on a fresh Debian 12 server on 3 November 2026. Free and open source under the GPL, from the VICIfast team.

What the installer does on Debian 12

The parts of a VICIdial scratch install that are particular to Debian 12, and that a by-hand install has to get right.

  • Debian 12 ships PHP 8.2, so PHP 8.3 comes from packages.sury.org, Debian’s PHP maintainer’s own repository.
  • Measured the fastest install of the tested systems.
  • AppArmor is removed, as VICIdial’s own Ubuntu instructions do: its daemons, AGIs and web code write across /etc/asterisk, /var/lib/asterisk and /var/spool/asterisk, and a confining profile breaks them.

FAQ

Questions, answered straight

Yes. The installer puts stock VICIdial r4035 on Debian 12 (bookworm) with PHP 8.3 from packages.sury.org, Debian’s MariaDB 10.11 and Asterisk 22.5.1-vf1 built for Debian 12.

Either: the installer does the same on both, and both are tested on every release. Debian 12 was the fastest install in our test runs; Ubuntu 24.04 takes PHP 8.3 from Ubuntu itself rather than a separate repository.

3m 20s from the start of the install to a working dialer, measured on a fresh 4 vCPU / 8 GB server with every option on and the prebuilt Asterisk. Compiling Asterisk on the server instead adds up to 3 minutes.

Run the same command again. It resumes at the stage that failed and keeps the passwords and options it already chose.
