I am having problem setting up Pi as Bluetooth headset - HSP profile (I do not need/want A2DP, HFP, etc. Just the simplest HSP.) In short, Pi should be seen as a headset by any device that can connect to BT headsets
OS: stretch (2017-11-29)
pulseaudio and ofono successfully installed as per https://scribles.net/enabling-hands-free-profile-on-raspberry-pi-raspbian-stretch-by-using-pulseaudio/
ASUS USB BT dongle is provisioned and recognized as per http://youness.net/raspberry-pi/bluetooth-headset-raspberry-pi-3-ad2p-hsp
Trusting and pairing work fine. Connecting fails after few seconds (it connects then immediately disconects.) The handset reports 'service not supported'. Obviously, headset profile is not listed (see below). Attempts to change class to something that looks like headset failed.
All help appreciated.

Edit: it works as headset only with MacBook Pro (Sierra) and nothing else (tried many handsets, Windows machines, etc.) What is special about MacBook?
It fails on everything else, after connecting, with:

- Manually install newer versions of Ofono (source) and Pulseaudio (from Buster packages)
Pulseaudio 11 package and and deps:
libpulse0_11.1-4_armhf.deb pulseaudio_11.1-4_armhf.deb pulseaudio-module-bluetooth_11.1-4_armhf.deb
No need to edit /etc/pulse/default.pa at all
Edit /etc/dbus-1/system.d/ofono.conf and add
(see https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/ for explanation)
