You'd need to use CreatePairedDevice if you want to pair. simple-agent
will also do it for you if you run it as "simple-agent hci0 <address>".

That's because your phone isn't a headset :)

The Audio interface at the moment only supports headset-like devices but
not devices having the opposite role (i.e. those that usually connect to
headsets), like your phone.

I think you'll need to explicitly enable the the experimental support for
that interface by adding Enable=Gateway to /etc/bluetooth/audio.conf.
However, even then you're likely to bump against problems since as I
mentioned the support is still completely experimental.

It is but the audio profiles don't really work yet. Other profiles your
headset supports will most likely work better.
