Getting back to the #librem5 #dogwood as a phone...
I’ve seen it make/receive calls. But, on at least 2 occasions, I've seen it not.
The phone status indicated it was on the cellular network. But, calls from 2 different phones didn't come through.
I tried to make a call, which it looked like it tried to do. The calls app froze and the called phones didn't ring. The red call-end button didn't do anything. I closed the app from phosh.
A recycle got things back working again.
