I've had my UC520W running for a couple of months now, but have noticed at least 2 of the 4 built-in FXO ports have died (yet to test the final 2). No lightning strikes to blame it on. Anyone know if this is a known weak point?
I got a SMARTNET quote @ $480, but as the unit only cost me $500...doubles my outlay

. Alternative is to get a VIC2-FXO @ $120...
Any thoughts or suggestions?
