Next time an FXO stops responding, stop asterisk and do a register dump 
of the offending module. You may need to cd into the zaptel src 
directory - I'm not sure that fxstest is installed.

./fxstest /dev/zap/1 regdump

will show you the contents of all the registers on Zap 1. If the 
majority of them show the value "ff", contact Digium support.

I had modules marked "Rev C" that did this replaced with "X100B RevB" 
ones and have not had any trouble since.
