Declining incoming call
Every time I decline an incoming call I get a missed call notification from my operator (Vodafone.de). The caller gets the voice info that I wasn't available and shortly after the call get's a SMS that I'm available again. I got the impression that Jolla sends a message to the operator that is not intended for declined calls. Instead of not available a rejected or busy indicator would be preferable.
I haven't found alternative methods in the dbus interface of active call, and couldn't browse the source code of the phone app, which seems to be closed source.
Are you aware of a way to change the way when rejecting a call?
