PhreakScript is also useful for:

  • automating installation and maintenance of Asterisk, Asterisk Test Suite, Asterisk Test Framework, DAHDI Linux, DAHDI Tools, and related resources
  • validating Asterisk configuration
    • can find common syntax errors in dialplan code
    • can find missing audio files referenced by the Playback, BackGround, and Read applications
    • suggests optimizations that can be made to dialplan code to make it more readable and efficient
  • generating Asterisk user documentation
  • debugging Asterisk configuration
  • generating core dumps
  • automating PhreakNet boilerplate dialplan installation

[1] Normally, PhreakScript installs the latest LTS version of Asterisk. However, version 21 will be installed by default until version 22 is released, due to the significant change in functionality from version 20 which allows for a richer installation by default. To install the latest LTS version (20), you can specify the version explicitly e.g. --version=20.5.0. However, there should not be a need to do so unless you are using obsolete modules that were removed in Asterisk 21.


Please refer to the Docs:

In a nutshell, run:


cd /usr/local/src && wget && chmod +x && ./ make


pkg install -y wget && cd /usr/local/src && wget && chmod +x && ./ make

Then, you can use PhreakScript. Run phreaknet help or phreaknet examples to get started.

For a basic install, you can run phreaknet install

To install with DAHDI, run phreaknet install --dahdi (add --drivers to also restore drivers that were removed upstream in DAHDI 3).

For a guided, interactive installation, you can also run phreaknet wizard. The wizard will determine what installation options are best for you, based on your preferences.

PhreakScript must be run as root, even if Asterisk does not run as root.

PhreakScript is primarily supported on Debian-based Linux systems. Support has also been added for FreeBSD. Pull requests to add support for other Linux distros or BSD are welcome.
