SIP SIMPLE client SDK
---------------------

Description
-----------
SIP SIMPLE client SDK is a Software Development Kit for easy development of
SIP end-points that support rich media like Audio, Instant Messaging, File
Transfers, Desktop Sharing and Presence. Other media types can be easily
added by using an extensible high-level API.
The software has undergone in the past years several interoperability tests
at SIPIT (http://www.sipit.net) and today is of industry strength quality.
Background
----------
SIP stands for 'Sessions Initiation Protocol', an IETF standard described by
RFC 3261. SIP is an application-layer control protocol that can establish,
modify and terminate multimedia sessions such as Internet telephony calls
(VoIP). Media can be added to (and removed from) an existing session.
SIP allows the endpoints to negotiate and combine any type of session they
mutually understand like video, instant messaging (IM), file transfer,
desktop sharing and provides a generic event notification system with
real-time publications and subscriptions about state changes that can be
used for asynchronous services like presence, message waiting indicator and
busy line appearance.
Features
--------
The library has cross platform capabilities on Linux OS, Mac OSX and
Microsoft Windows. The library should work with minimal changes on any
platform that supports C and Python development environments.
The SDK is suitable for building end-points like SIP clients or SIP
Application Servers. To see what the SDK is capable of, you can try Blink
from http://icanblink.com

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
----
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.
Twisted
-------
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).

have. It is available under the MIT License.
Python-xcaplib
--------------
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.
Pjlib
-----
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
