[cisco-voip] H.323 Gateway DSP problem

[Greg Ayoub]

I have a 2801 with a DSPVM and a 4 port FXO card configured as an H.323 
gateway to cisco callmanager 4.13.   Every several days, we get all busy 
signals even though all lines are on hook, and the only way I can correct 
the problem is to reset the DSPs.  Here is the show log output after issuing 
the commands

test voice port 0/0/0 si-reg-read 39 1
test voice port 0/0/0 codec-debug 10 0


Note the error below: "On_hook line reversal detected possibily due to 
crossed cable."  We are sure that cables and wires are not crossed, is there 
anything else that might cause this error message?  My initial thoughts were 
it might be a voltage problem from the fxs ports on the PBX?
