Can't call or receive calls

[PJK2012]

I've had my PinePhone for quite a while, but only recently got a SIM for it. Calling and receiving calls is not working, I was told to change from ofono to ModemManager with this command:

sudo systemctl disable --now ofono ofonoctl && sudo systemctl enable --now ModemManager

Terminal accepted the command, but calling and receiving calls still doesn't work. Oddly when calling the PinePhone the screen will briefly dim in sync with each call ring heard in the calling phone.

In the GUI settings looks like this:

SIM 0 - SIM Details

Operator Name - T-Mobile

Modem Details

Enabled - true

State - Disabled

Failure Reason - No error

This is the standard PinePhone current edition shipping stock with Manjaro.

I have partially solved the problem by downloading and flashing the current OS file. Now the Pinephone will make a call and rings when there is an incoming call, but nothing happens when I press "Accept" for an incoming call.

After a few reboots the behavior has gotten more in line with the gitlab issue reports. If the phone is with screen off, it will ring, but pressing accept to answer won't work until I unlock the phone. On the other hand, leaving the screen on with the phone unlocked, the phone doesn't ring, but I can accept a call. So this proves all functions work, just not consistently. So I am marking this thread solved.
