<h2>Welcome to <a href='https://www.doubango.org'>doubango</a> project!</h2>
<p><a href='http://en.wikipedia.org/wiki/IP_Multimedia_Subsystem'>3GPP IMS</a> (IP Multimedia Subsystem) is the next generation network for delivering<br>
IP multimedia services. IMS is standardized by the 3rd Generation Partnership Project (3GPP). <br />
IMS services could be used over any type of network, such as <a href='http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution'>3GPP LTE</a>, GPRS, Wireless LAN, CDMA2000 or fixed line.<br>
</p>
<p>
<a href='https://www.doubango.org'>doubango</a> is a mature, open source, 3GPP IMS/LTE framework for both embedded and desktop systems.<br />
The framework is written in ANSI-C to ease portability and has been carefully designed to efficiently work on embedded systems with limited memory and low computing power and to be extremely portable.</p>
