It looks like you dropped some word(s) from your sentence. Was there something
in the log you wanted to highlight? From the log it looks like the UUIDs
changed all of a sudden, which would be weird, but maybe that's happening
because this was the first time trying with a new version of bluetoothd that
doesn't any more modify the UUID list from the device, and the old UUIDs were
from some database of bluetoothd that still contained the UUIDs from the old
bluetoothd version.

Otherwise I don't see anything strange in the log.

What do you mean by that?

You could attach the verbose log from the pulseaudio daemon.

That patch is a part of a series. The patches are relevant if you have an
HFP-only headset. The patches shouldn't be needed if the headset supports HSP.

The patches probably won't apply cleanly to the current master. Somebody tried
it once, and after it failed, I made a git branch available with the patches
applied here: https://cgit.freedesktop.org/~tanuk/pulseaudio/ (branch "hfp").

The patches have been reviewed, but not applied upstream, because they had
issues. The original author never sent an updated version of the patches. If
someone would like to finish the work, you can see the review feedback in
patchwork:
