Asterisk is distributed under the GNU General Public License version 2
|
||
|
and is also available under alternative licenses negotiated directly
|
||
|
with Digium, Inc. If you obtained Asterisk under the GPL, then the GPL
|
||
|
applies to all loadable 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. These components are also distributed under the
|
||
|
GPL version 2 as well.
|
||
|
|
||
|
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, OpenH323
|
||
|
UniMRCP, and/or the UW IMAP Toolkit and distribute the resulting binary files.
|
||
|
|
||
|
In addition, Asterisk implements several management/control protocols.
|
||
|
This includes the Asterisk Manager Interface (AMI), the Asterisk Gateway
|
||
|
Interface (AGI), and the Asterisk REST Interface (ARI). 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.

wish to use these trademarks for purposes other than simple
|
||
|
redistribution of Asterisk source code obtained from Digium, you
