I'm developing my own sip client. My application is in the background and
I'm using the telephone native gui.

I need help with the following issues:

1) when I receive incoming sip call I would like to pop up a dialog such as
in voice calls (the same way as the telephone application does).
I think that I need to use the etel server to send message to the telephone
native application but I don't know how.

2)when I receive sip incoming call I would like to play the current phone ringer. Can anyone please give me instruction how to do it?
