Licenses for Dependencies
This section describes the licenses for the SIP SIMPLE client SDK and its dependencies.
Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform), it is available under the MIT License.
Libxslt is a language for transforming XML documents into other XML documents. It is available under the MIT License.
GnuTLS is a project that aims to develop a library which provides a secure layer, over a reliable transport layer. Currently the GnuTLS library implements the proposed standards by the IETF's TLS working group. The library is licensed under the GNU Lesser General Public License version 2.1.
Download, build, install, upgrade, and uninstall Python packages. It is available under the Python Software Foundation License.
A language that makes writing C extensions for the Python language as easy as Python itself. Cython is available under the open source Apache License.
A collection of modules that are useful when building python applications. Their purpose is to eliminate the need to divert resources into implementing the small tasks that every application needs to do in order to run successfully and focus instead on the application logic itself. Is available under GNU Library or Lesser General Public License (LGPL).
A DNS toolkit for Python. It supports almost all record types. It can be used for queries, zone transfers, and dynamic updates. Dnspython originated at Nominum where it was developed to facilitate the testing of DNS software. Nominum has generously allowed it to be open sourced under a BSD-style license.
Lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. A Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API. The lxml library is shipped under a BSD license.
A networking engine written in Python, supporting numerous protocols. It contains a web server, numerous chat clients, chat servers, mail servers, and more. The source code is available under a proprietary license (non GPL).
The pylib is a development support library featuring py.test, ad-hoc distributed execution, micro-threads (greenlets) and uniform local path and svn abstractions. Is provided under MIT License.
Python wrapper for gnutls available under either GPL or Lesser General Public License (LGPL).
Eventlet makes asynchronous programming look like synchronous, thus achieving higher signal-to-noise ratio than traditional twisted programs have. It is available under the MIT License.
XCAP protocol, defined in RFC 4825, allows a client to read, write, and modify application configuration data stored in XML format on a server. XCAP maps XML document sub-trees and element attributes to HTTP URIs, so that these components can be directly accessed by HTTP. An XCAP server used by XCAP clients to store data like presence policy in combination with a SIP Presence server that supports PUBLISH/SUBSCRIBE/NOTIFY SIP methods can provide a complete SIP SIMPLE solution. The XCAP client example script provided by this package can be used to manage documents on an XCAP server. The software is available under either GPL or Lesser General Public License (LGPL).
PortAudio is a free, cross platform, open-source, audio I/O library. It lets you write simple audio programs in 'C' that will compile and run on many platforms including Windows, Macintosh (8,9,X), Unix (OSS), SGI, and BeOS. PortAudio is intended to promote the exchange of audio synthesis software between developers on different platforms. The PortAudio licence is a plain MIT licence.
A small footprint, high performance, ultra portable abstraction library and framework, used by PJSIP and PJMEDIA. PJLIB is about the only library that PJLIB-UTIL, PJMEDIA, and PJSIP should depend, as it provides complete abstraction not only to Operating System dependent features, but it is also designed to abstract LIBC and provides some useful data structures too. A cross-platforms portability and framework library. Available under GPL or an alternative non-GPL license.
PJLIB-UTIL is an auxiliary library providing supports for PJMEDIA and PJSIP. Some of the functions/components in this library: small footprint XML parsing, STUN client library, asynchronous/caching DNS resolver, hashing/encryption functions, etc. Available under GPL or an alternative non-GPL license.
PJNATH is a new library, available in the SVN trunk, for helping the applications with NAT traversal. It implements the latest specification of Session Traversal Utilities for NAT (STUN), Obtaining Relay Addresses from STUN (TURN), and Interactive Connectivity Establishment (ICE). Available under GPL or alternative non-GPL license.
PJMEDIA is a complementary library for PJSIP to build a complete, full-featured SIP user agent applications such as softphones/hardphones, gateways, or B2BUA. Available under GPL or an alternative non-GPL license.
A placeholder library to support various multimedia codecs. Available under GPL or an alternative non-GPL license.
A SIP protocol stack, the main bulding block for this project. Available under GPL or an alternative non-GPL license. The non-GPL license is available from its licensor for a one time fee.
Eventlet is a networking library written in Python. It achieves high scalability by using non-blocking io while at the same time retaining high programmer usability by using coroutines to make the non-blocking io operations appear blocking at the source code level. It is available under MIT license.
Lightweight in-process concurrent programming. The "greenlet" package is a spin-off of Stackless, a version of CPython that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on "channels". It is provided under MIT license.
