The issue is most probably that your headset implements the HFP profile,
but not the HSP profile, and pulseaudio does not yet support the HFP
profile despite what that line says (HSP/HFP). To confirm, run
bluetoothctl, and type something like:
> devices
(...)
> info 11:22:33:44:55:66
Where the address is the one for your headset. It will likely display
something like this:
UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb)
UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb)
UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb)
UUID: Handsfree (0000111e-0000-1000-8000-00805f9b34fb)
If so, the "Headset" (HSP) profile is missing.

Title:
Bluetooth headset HSP/HFP mode not working in Bionic
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
There is a previous bug with almost the same title, but for Xenial
(https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1549163). I
have had this issue in Artful, and when commented on the old bug, I
was asked to raise a new one instead. I waited to see if Bionic fixed
it for me, but it does not seem to work still. So!
Steps to reproduce:
1. enable bluetooth on computer and switch on the headset.
2. pair and connect the headset
3. go to settings to switch headset to HSP/HFP mode to enable mic
4. save and close window.
Expected behaviour:
1. mic should be enabled and headset should be usable to attend calls on
laptop.
Behaviour in error:
1. Headset profile switches back to A2DP and mic is not enabled.
I am using a generic bluetooth headset on a fresh updated Kubuntu
18.04 bionic with plasma DE.
Software versions:
Kernel: 4.15.0-20-generic
Bluez version: 5.48-0ubuntu3
pulseaudio: 1:11.1-1ubuntu7
pulseaudio-module-bluetooth: 1:11.1-1ubuntu7
Additional information:
Running "pacmd list-cards" says that HSF/HFP is 'not available' on the
headset:
Output from Headset section:
profiles:
a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 40,
available: unknown)
headset_head_unit: Headset Head Unit (HSP/HFP) (priority 30,
available: no)
off: Off (priority 0, available: yes)
active profile: <a2dp_sink>
