I think I've found where the polarity reversal is going ... I think my 
lightning/spike filter is eating it or something.

When I look at the syslog with the filter removed I see messages about 
polarity reversals.

With the filter they are missing.

Yet the phones I normally have plugged in still seem to read the CLI 
with no difficulty with or without the filter, and the SPA can't read 
them with or without the filter. Very fustrating.

Yes, it is a bog standard BT line.

I've tried using the CLI detection mode without the "PR" but that 
doesn't work either.

I'm not sure what to try next....
