=== Asterisk Add-on Modules ===
|
||
|
|
===============================================================================
|
||
|
|
|
||
|
|
This document pertains to the modules that reside in the addons/
|
||
|
|
subdirectory of the source tree. By default, these modules are not compiled
|
||
|
|
and installed. If you choose to enable them, you must be aware of what
|
||
|
|
potential licensing and/or patent implications that has on your usage and
|
||
|
|
distribution of Asterisk.
|
||
|
|
|
||
|
|
Even though Asterisk is released as open source under the terms of the
|
||
|
|
GPLv2 (see LICENSE for details), no core functionality in Asterisk has any
|
||
|
|
dependencies on libraries that are licensed under the GPL. One reason a module
|
||
|
|
may be in the add-ons category is that it may have a GPL dependency. Since
|
||
|
|
these dependencies are not compatible with dual licensing of Asterisk, the
|
||
|
|
dependant modules are set aside to make it clear that they may not be used
|
||
|
|
with commercial versions of Asterisk, unless other licensing arrangements are
|
||
|
|
made with the copyright holders of those dependencies.
|
||
|
|
|
||
|
|
Another reason that modules may be set aside is that there may be
|
||
|
|
additional restrictions on the usage of the code imposed by the license or
|
||
|
|
related patents. The MySQL and MP3 modules are examples of this.
