I have a theory that Bose devices are probably just noticing they've been connected in HSP mode by default and that's when they say "call from". In that case this might be fixed with bug 1720684, so keep an eye on that one.

My headset seems to think a connection to a phone call is taking place. This is annoying because the audio will start to play and after a little while the "call from" voice talks over the audio.
