in a nutshell, things seem to be good from the ofono-phonesim perspective in terms of modems, but I still can't get HFP audio telephony to work for calls (meanwhile A2DP works flawlessly for music playback).
I'm on Ubuntu 20.04 Focal Fossa, arm64.
This is a follow up to my earlier question. It may seem to be a duplicate of this question but, my use case is the opposite, as I'm trying to use the Linux machine's USB peripherals ($15 mic and $15 speaker bar) as the Headset Unit role, and a mobile device as the Audio Gateway.
Additionally, I've attempted the top answer, specifically everything up to this point:
ofono-phonesim -p 12345 /usr/share/phonesim/default.xml
with
dbus-send --print-reply --system --dest=org.ofono /phonesim org.ofono.Modem.SetProperty string:"Powered" variant:boolean:"true"
and
/ofono/test$ ./enable-modem
and it looks like I'm good from a modem perpective, however I still get no audio for telephony, and I get "Failed to change profile to headset_audio_gateway" in blueman when i try to set the Smart Phone to Headset Audio Gateway (HSP/HFP) manually.
Here's the output for ~/ofono/test/list-modems:

bluetoothd only seems to give useful info related to A2DP.
Any ideas? Has anyone gotten this to work with the phone as the Audio Gateway?
edit:
cat /var/log/syslog* | grep -i pulse shows [datetime][machine] pulseaudio[839]: Refused to switch profile to headset_audio_gateway: Not connected after attempting to switch to HFP manually in blueman.
Update Feb 24 2022:
So I realized that I had headset=native set in /etc/pulse/default.pa, from some earlier testing where I was trying to ensure HSP instead of HFP. So now that i've set headset=ofono I'm no longer getting an error message "Failed to change profile to headset_audio_gateway" when I switch to HFP.

So at least I see headset_audio_gateway: Headset Audio Gateway (HSP/HFP) (priority 10, available: yes) now. Now the issue is it seems like I can switch to HSP/HFP okay, but I'm still getting silence. This was the same result I would get with HSP before installing ofono & ofono-phonesim.
last piece of new info from cat /var/log/syslog* | grep -i pulse: pulseaudio[882]: Deferred setup faild on fd -1: Transport endpoint is not connected. Not exactly sure what this means or if it's relevant but looks to be a new error.
