I was wondering if FXO ports support custoPAK phone lines from Verizon.
A customer has such lines with all features turned off (they are centrex lines).
Is it possible that such a line if not configured correctly can cause damage
to DSPs onboard? The customer had 3 RMAs so far (not all for the
same reason though).
Does the uc520 need to be configured specially to handle these lines?
Supposedly they are simple centrex lines. I was told by verizon the customer
should not configure the FXO for a "ground start" line but for a "loop start" line.
Can you even change such setting via the CCA? Would it cause outsiders
to sporadically observe "all lines busy" when calling the customer, even if the lines aren't
used at all? what else could cause such sporadic behavior?
Last, can features such as call waiting, caller id and and anonymous-call-rejection
influence whether uc520 works correctly with custoPAK lines (in other words do they need
to keep them off, or can they turn them back on for those lines?)
Thanks very much,
