Thank-you for the feedback.

I notice the audio quality as white background noise, even during the 
dial tone or the silent period after dialing and before ringing.  I 
don't believe it is codec related as I haven't noticed a difference when 
trying different ones.  Adjusting the audio gain didn't seem to help.

As an aside, with regards to audio gain it took me a while to realise 
their "handset in" and "handset out" setting options were the opposite 
of what I thought.  "handset in" is the audio gain setting on the audio 
going in to the S100-FX from the handset (what I would have called 
'handset out' or 'in from handset') and "handset out" is the audio gain 
setting on the audio going out of the S100-FX to the handset (what I 
would have called 'handset in' or 'out to handset').

Would the registry interval be what they call the "register ttl" 
setting?  I haven't tried changing mine, but from the configuration page 
it appears to be adjustable.

If you're unable to change yours you might want to confirm that you have 
the most recent firmware.  When I emailed x100p asking about the most 
recent firmware this is the link they sent:

Dear Customer,
