[Asterisk-Users] line battery check

[Jared Smith]

There's got to be a way... I think zttool shows a red alarm on an X100P
when there's no phone line plugged into it (and I would guess when
there's no voltage on the line.)  My guess is that it gets the info from
/proc/zap-something-or-other, but I'm just guessing.
