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. + + If you have any questions, contact your lawyer. + +=============================================================================== +=============================================================================== |
