That was just a test code. I also tried it with com.nokia.csd.Call.
But it is still failing.

Yes. My sendDTMF() function is generic and does the parsing, etc. The
problem is that the connect is failing. I also tried pasting your code
and using QDBusConnection::SystemBus() directly. But it is still
failing. My other DBus methods works, only the connect is failing.

Further ideas would be of great help. If you can pull the source from
the repository and see what the error might be, it would be great.
This is the only obstacle to get my application complete.

Does the application need signing or additional priviledges to get
such connections?
