<p class="body_text" align="left">
|
|
<strong>doubango</strong> is an experimental cross-platform, open source 3GPP NGN/IMS
|
|
framework for embedded systems (it also works on Windows XP/Vista/7, Mac OS X and
|
|
unix-like systems).
|
|
<br />
|
|
The framework has been carefully designed to efficiently work on embedded systems
|
|
with limited memory and low computing power and to be extremely portable.<br />

<strong><span style="font-size: 12pt; text-decoration: underline">SIP/IMS Stack</span><br />
|
|
</strong>
|
|
<br />
|
|
The SIP/IMS stack (<a href="http://tools.ietf.org/html/rfc3261" rel="nofollow"><span
|
|
style="text-decoration: underline">RFC 3261</span></a>) implements <a href="http://www.3gpp.org/ftp/Specs/html-info/24229.htm"
|
|
rel="nofollow"><span style="text-decoration: underline">3GPP TS 24.229 Rel-9</span></a><span
|
|
style="text-decoration: underline"> </span>and can be used to develop
|
|
VoIP applications targeting embedded systems, desktop computers, laptops, tablet
|
|
PCs or handheld PCs.<br />
|
|
You can also use the stack to develop IM clients (Both <b>Page Mode</b> and <b>Session
|
|
Mode</b>) using <a href="http://en.wikipedia.org/wiki/SIMPLE">SIMPLE protocol</a>.
|
|
Almost all SIP methods are supported (<b>INVITE</b>, <b>MESSAGE</b>, <b>REFER</b>,
|
|
<b>UPDATE</b>, <b>INFO</b> ...) and the stack could be easily extended to implement
|
|
any missing or custom method.<br />
|
|
The Stack contains both <a href="http://en.wikipedia.org/wiki/Multimedia_Telephony_(MMTel)">
|
|
MMTel</a> and <a href="http://en.wikipedia.org/wiki/Push_to_talk">PoC</a> extensions
|
|
to allow developing rich multimedia applications.<br />
|
|
The transport layer offers possibilities to use <b>UDP</b>, <b>TCP</b>, <b>TLS</b>
|
|
or <b>SCTP</b> protocols.

To ease portability, <strong>doubango</strong> framework contains several platform

independent network stacks such as <b>HTTP/HTTPS</b>(<span style="text-decoration: underline">RFC

NAT traversal is a key feature for any VoIP application and allows media (RTCP/RTP)

|
|
Symmetric Response Routing (<span style="text-decoration: underline">RFC 3581</span>)

ICE makes use of STUN protocol and its extension, traversal Using Relay NAT (<a href="http://en.wikipedia.org/wiki/Traversal_Using_Relay_NAT">TURN</a>)

The media framework uses <a href="http://www.gstreamer.net" rel="nofollow">GStreamer</a>
