BRIstuffed Asterisk is distributed under the GNU General Public License version 2 and is not available under any alternative licenses. If you obtained BRIstuffed Asterisk under the GPL, then the GPL applies to all loadable BRIstuffed Asterisk modules used on your system as well, except as defined below. The GPL (version 2) is included in this source tree in the file COPYING. This package also includes various components that are not part of Asterisk itself; these components are in the 'contrib' directory and its subdirectories. Most of these components are also distributed under the GPL version 2 as well, except for the following: contrib/firmware/iax/iaxy.bin: This file is Copyright (C) Digium, Inc. and is licensed for use with Digium IAXy hardware devices only. It can be distributed freely as long as the distribution is in the original form present in this package (not reformatted or modified). Digium, Inc. (formerly Linux Support Services) holds copyright and/or sufficient licenses to all components of the Asterisk package, and therefore can grant, at its sole discretion, the ability for companies, individuals, or organizations to create proprietary or Open Source (even if not GPL) modules which may be dynamically linked at runtime with the portions of Asterisk which fall under our copyright/license umbrella, or are distributed under more flexible licenses than GPL. If you wish to use our code in other GPL programs, don't worry -- there is no requirement that you provide the same exception in your GPL'd products (although if you've written a module for Asterisk we would strongly encourage you to make the same exception that we do). Specific permission is also granted to link Asterisk with OpenSSL and OpenH323 and distribute the resulting binary files. In addition, Asterisk implements two management/control protocols: the Asterisk Manager Interface (AMI) and the Asterisk Gateway Interface (AGI). It is our belief that applications using these protocols to manage or control an Asterisk instance do not have to be licensed under the GPL or a compatible license, as we believe these protocols do not create a 'derivative work' as referred to in the GPL. However, should any court or other judiciary body find that these protocols do fall under the terms of the GPL, then we hereby grant you a license to use these protocols in combination with Asterisk in external applications licensed under any license you wish. The 'Asterisk' name and logos are trademarks owned by Digium, Inc., and use of them is subject to our trademark licensing policies. If you wish to use these trademarks for purposes other than simple redistribution of Asterisk source code obtained from Digium, you should contact our licensing department to determine the necessary steps you must take.
