Welcome to doubango project!

3GPP IMS (IP Multimedia Subsystem) is the next generation network for delivering
IP multimedia services. IMS is standardized by the 3rd Generation Partnership Project (3GPP).
IMS services could be used over any type of network, such as 3GPP LTE, GPRS, Wireless LAN, CDMA2000 or fixed line.

doubango is a mature, open source, 3GPP IMS/LTE framework for both embedded and desktop systems.
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.

Proof Of Concept

Client-side components
Boghe - SIP Video Client for Windows Phone 8 and Surface Pro
- IMS/RCS Client for Windows XP, Vista, 7 and 8
IMSDroid SIP/IMS Client for Android
iDoubs SIP/IMS VideoPhone for iOS (iPhone, iPad and iPod Touch) and MAC OS X

Server-side components webrtc2sip Smart SIP and Media Gateway to connect WebRTC endpoints to any SIP-legacy network telepresence the open source SIP TelePresence system with a porwerfull MCU Flash2IMS Adobe® Flash® to SIP/IMS Gateway.
