I am very pleased to announce version 0.4.0 of the Decibel
Realtime
Communication Framework.
Decibel
=========
Decibel is a realtime communications framework, meant to
integrate services
like CTI (Computer Telephone Integration), VoIP (Voice over
IP), text based
chat and instant messaging.
End users find in Decibel one central place to manage all
realtime
communication settings and can easily configure and change
responses to
communication requests.
By providing a simple, DBus-based API to the services like
communication
account management, connection to contacts, etc. Decibel
reduces the
complexity and effort of accessing realtime communication
technologies in
applications. This allows for integration of realtime
communication
technologies into applications that are not focused on
communication.
Decibel consists of the desktop neutral policy daemon and
desktop dependent
components. These components interact with the user and his
desktop
environment by providing GUIs for common tasks like eg.
creating a new
communication account, storing passwords or contacting a
friend. Using the
Telepathy specification (http://telepathy.fr
eedesktop.org/) the Decibel
daemon manages Telepathy compliant connection managers
(implementing the
various communication protocols) and connects them to
Decibel components as
required by the users communication needs.
Motivation
----------
Today's users are relying on communication software on their
computer systems.
They are forced to switch between different applications for
the different
protocols and communication methods (text chat, telephony,
etc.) they
are using. These applications usually are poorly integrated
with each other,
thus requiring the users to interact with several
applications to do simple
things like setting their online status to "away"
on all communication
channels they are using.
Acknowledgments
---------------
Development of Decibel is sponsored by NLnet (http://www.nlnet.com/) and
basysKom GmbH (http://www.basyskom.de/).
Thanks for the support you are giving!
I further want to thank the Tapioca project
(http://tapioca-v
oip.sourceforge.net/) for providing Qt bindings
to the telepathy specification Decibel is using.
License
-------
Decibel is released under the LGPL version 2.1.
Version 0.4.0
===============
This release is considered to be a feature complete
implementation of the
Decibel daemon. It does:
* Manage communication accounts for all supported
protocols
* Listen for incoming and outgoing communication channels
* Start up components as configured to handle these
channels
* Support profiles of component configurations. This way
you can eg. have
different reactions to incoming communication channels
when online or
offline.
* Create connections to contacts managed in an external PIM
system.
* Propagate presence state of contacts into an external PIM
system.
Please send a email to tobias dot hunger at basyskom dot de
if you think we
can improve support for your use cases.
Version 0.4.0 includes an example implementation
demonstrating how to
integrate Decibel with a desktop environment. This
implementation uses simple
INI files for data storage.
This is the forth milestone release of Decibel. It is
addressed to application
developers wanting to get a glance at Decibel. We are very
much interested
in your feedback (and - of course - contributions !
Changes since Version 0.3.0
=============================
* Build with -fvisibility=hidden: This is the default with
KDE4
* miniGUI VoIP/CTI client added. this is an example
application working well
with the snom telepathy module available here:
http://decibel
.kde.org/index.php?id=90
* Documentation updated and reworked. Common API part was
split out to
avoid confusing doxygen.
* API improvements in the ContactManager:
Contacts are no longer required to be registered with the
PIM system.
Sources:
==========
Get the sources at http://decibel
.kde.org/index.php?id=90
The code is further available in the KDE Subversion
repository:
svn://anonsvn.kde.org/home/kde/branches/work/decibel
Please see the INSTALL file for instructions on how to build
the sources and
the a list of dependencies.
If you have questions or comments, please send an email to
tobias dot hunger at basyskom dot de
Thanks!
Binary packages are not available from us, but some linux
distributions
already ship Decibel packages. See http://decibel
.kde.org/index.php?id=90
for a list of links.
Known Problems
================
None.
To Do
======
* Update to the newest telepathy specification. This will
improve
compatibility
to telepathy connection managers using the streamed media
interface.
* Finalize KDE4 Controlcenter Module for account handling,
add another module
to configure components.
* Integrate Decibel into desktop environments: A second
example
implementation
showing how to integrate Decibel into KDE4 needs to be
added.
* Enhance existing command line examples with a GUI and
write more examples.
