titleWhich version should I install?
  • If you want a rock solid communications framework, choose the latest Long Term Support (LTS) release.
  • If you want the latest cool features and capabilities, choose the latest release of Asterisk. If that is a Standard release, note that these releases may have larger changes made in them than LTS releases.

Unless otherwise noted, for the purposes of this section we will assume that Asterisk 14 is being installed.

Review Asterisk's System Requirements in order to determine what needs to be installed for the version of Asterisk you are installing. While Asterisk will look for any missing system requirements during compilation, it's often best to install these prior to configuring and compiling Asterisk.

Asterisk does come with a script, install_prereq, to aid in this process. If you'd like to use this script, download Asterisk first, then see Checking Asterisk Requirements for instructions on using this script to install prerequisites for your version of Asterisk.
