I have the same issue.

Two headsets:

Both devices give the same error when trying to switch to HSP/HFP:

W: [pulseaudio] module-bluez5-device.c: Refused to switch profile to
headset_head_unit: Not connected

Both devices show the profile is not available:

        Profiles:
                a2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1,
sources: 0, priority: 10, available: yes)
                headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1,
sources: 1, priority: 20, available: no)
                off: Off (sinks: 0, sources: 0, priority: 0, available: yes)

I don't know where to go from here.

Bluez 5.36
PulseAudio 8.0

I have also built and installed Bluez 5.39 but it didn't help.

Additional information:

This laptop (Lenovo X260) is running Debian stretch.  No GDM, I just run startx
after logging in, pulseaudio runs as my user account. (I saw some other
bugreports where GDM runs pulseaudio as a different user and that causes
issues)

This laptop will replace my old Lenovo T420 which runs Debian wheezy(?) and on
which both of these headsets work in both A2DP and HSP/HFP.

I use a softphone (linphone) with these bluetooth headsets all the time for my
work -- I do software demos and webinars by phone a few times a day.  So I have
been trying to get this to work for the last couple of days as I prepare this
new laptop to replace my old one, but I don't know what else to try.
