Plasma-dialer should recognize when incoming call is accepted elsewhere e.g. by Bluetooth device
In a not-so-distant future, Bluetooth connection between Linux phones and external audio devices will reach (almost) feature parity with Android/iOS phones, meaning it will be possible to accept/reject calls from e.g. car's steering wheel buttons. This is thanks to this Pulseaudio MR, that will be soon implemented in unstable distributions like pmOS edge.
While testing this by manually applying the MR on top of pmOS edge image, looks like plasma-dialer does not manage when a call is accepted from BT device commands, while gnome-calls does. Both photos are at this commit.
As you can see in the image, when accepting incoming call using streering wheel's commands, call is started (confirmed at network operator's) but plasma-dialer goes on ringing.
And, please, keep up your good work done on plasma-dialer so far!
