[maemo-developers] QDBusError UnknownMethod for com.nokia.csd.Call service

[From: Daniil Ivanov]

Hi Roman!

  Sorry, my fault. It should be something like this

QDBusConnection connSystemBus = QDBusConnection::systemBus();
QDBusInterface dbusPhone( "com.nokia.csd.Call", "/com/nokia/csd/call",
"com.nokia.csd.Call", connSystemBus );
QDBusMessage reply = dbusPhone.call( "CreateWith", "+43123456789",(uint)0 );

Thanks, Daniil.
