Found Potential Fix For Pinephone/Verizon

[syrinx]

While I was on the phone with Verizon tech support, I was throwing AT commands at the modem just for kicks. Through dumb luck, I managed to get calling, texting and data working. This took me from calls never going through and occasionally crashing the dialer to them being as smooth as I could hope for on experimental software. The only difference between a base pmOS phosh install and mine is that I have nano and minicom installed. Here are my steps:

List VoLTE configs:
# echo 'AT+QMBNCFG="list"' | atinout - /dev/EG25.AT -

Select proper config, in my case Verizon:
# echo 'AT+QMBNCFG="select","hVoLTE-Verizon"' | atinout - /dev/EG25.AT -

Restart modem:
# echo 'AT+QCFG="ims",1' | atinout - /dev/EG25.AT -

Restart phone.
After that, everything worked
