QjSimple is a prototype implementation of a cross-platform SIP Client. It is based on the pjsip SIP stack and the Qt GUI toolkit.

QjSimple can be seen as developer tool and supports the following features:
QjSimple's underlying SIP stack is IETF SIP compatible. Thus, QjSimple is compatible with all SIP providers which are also IETF compatible, e.g. iptel.org, A1overIP, sipgate, gizmo, ...
Source Code
QjSimple is open source licensed under GPL, thus full source code and project files are available.
Binaries
Binaries for Windows (18.5MB) include the necessary Qt and mingw DLLs (the binaries are big becauese it is a debug-build). The binaries for Mac OS X do not contain the Qt libraries, thus you have to install them before.
Development
QjSimple development uses Mingw and Eclipse, but other IDEs can be used too. For usage and build instructions please refer to the readme.txt file.
QjSimple is licensed under GPL - if you need a different license model please contact us.
