Yay, thank you very much!

It looks that QtDBus is exactly what we need and looks also simplest. (I guess I was little confused with using dbus commands with QtDBus.)

If it won't work, I'll look at the others, but I would like to use simplest solution :3.

But I have one more question; do you know some reference, list of dbus commands? I tried Google, found many about SMS, making calls, setting profiles etc., but I also need detect when outgoing call occures and when call (in and also out) ends.

Thank you very much for your help
