The UniMRCP project distributes Asterisk modules that integrate Asterisk with UniMRCP, and other Asterisk users use the UniMRCP library as well. Unfortunately, the UniMRCP license is Apache 2.0, which per the Free Software Foundation, is not a compatible license with the GPLv2. "Please note that this license is not compatible with GPL version 2, because it has some requirements that are not in that GPL version. These include certain patent termination and indemnification provisions. The patent termination provision is a good thing, which is why we recommend the Apache 2.0 license for substantial programs over other lax permissive licenses." On the other hand, UniMRCP is a great project and we'd like to let people use it with Asterisk. This patch updates the LICENSE text to allow users to link Asterisk with UniMRCP and distribute the resulting binaries. ........

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 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.

redistribution of Asterisk source code obtained from Digium, you
