[cisco-voip] Disconnect of the plar connection to the ccm

See my post entitled '"show voice trace" and "battery-reversal
answer"' which no one responded to yet and I really think might be
relevant.
There are states and events for the FXO port in question that "show
voice trace" that I saw when I was having a similar problem. If this
is the cause then it has nothing to do with the stuff your debugging,
but rather with errors at the FXO state machine level which are
propagating (back).
Does this make sense or am I way off track?
Best,
leb
