News.
it is good or bad depends on your own preference.

I have tested the last build (wip0.19 available in my signature) without AD and calls worked as expected. Everything. Inbound/outbound. There were no issues with audio, ear piece, loudspeaker and microphone.
So, the strange behaviour is definitely related to the AD, moreover I think to one of the android app I installed. (I suspect the linphone.)
I'll too test that and report back.
