This application uses Doubango Framework.
The source code is under branches/2.0 and depends on doubango v2.x
To build the source code: http://code.google.com/p/idoubs/wiki/Building_iDoubs_v2_x

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.
iDoubs v2.x is the first fully featured open source 3GPP IMS Client for iOS devices (iPhone, iPod Touch and iPad). The main purpose of the project is to exhibit doubango's features and to offer an IMS client to the open source community. doubango is an experimental, open source, 3GPP IMS/LTE framework for both embedded (Android, Windows Mobile, Symbian, iPhone, iPad, ...) and desktop systems (Windows XP/Vista/7, MAC OS X, Linux, ...) and is written in ANSI-C to ease portability. The framework has been carefully designed to efficiently work on embedded systems with limited memory and low computing power.
As the SIP implementation follows RFC 3261 and 3GPP TS 24.229 Rel-9 specifications, this will allow you to connect to any compliant SIP registrar.
The current version of iDoubs partially implements GSMA Rich Communication Suite release 3 and The One Voice profile V1.0.0 (LTE/4G, also known as GSMA VoLTE) specifications. Missing features will be implemented in the next releases. Stay tuned.
