Source Code

If you need additional information about installing Asterisk from source code, read the installation guide on the Wiki.

Code can be checked out from the Git servers via anonymous read-only access. Development code can also be checked out from the Asterisk and libpri Gerrit repositories, and DAHDI Git repository. Below are example commands you might use to download the source from the various repositories.

# cd /usr/src

# git clone asterisk
# git clone git:// dahdi-linux
# git clone git:// dahdi-tools
# git clone libpri

To clone only a specific Asterisk branch from Gerrit, use the following format:

# git clone -b X asterisk-X

(with X being the current release and revision number). Example:

Note: The below example may not reflect the current release to date.

# git clone -b 13 asterisk-13

An important note

If you are intending to install a specific branch then it is best to clone that branch only and avoid cloning the entire repository.

If you have further questions or intend to push code back up to the repo please see the detailed Gerrit Usage instructions on the wiki.

ALERT: Asterix Open Source PBX is NOT associated with Sangoma Technologies

It has come to Sangoma’s attention that a company, or individual, is auto dialling people congratulating them on downloading Asterisk and offering Support and other products. We would categorically like to state that “Asterix Open Source PBX” is in no way associated with Sangoma. The first we were aware of these spam calls was when we were contacted by someone who hasn’t downloaded Asterisk – this leads us to believe that the people behind this are calling random numbers.
