Odorik app for iPhone, iPod
Odorik is an iOS application that allows you comfortably set up callbacks through your account with Czech VOIP provider of the same name, Odorik.cz (run by miniTEL s.r.o.).
While the app’s support for Odorik’s services isn’t 100% it has the basic functionality of setting up callbacks and displaying call history. The rest of the features (namely sending SMS) will follow in future versions of the app.
Also, you can check the the source code on GitHub; it’s released under GPLv2.
Support is conducted via email, don’t hesitate to write us.
