This tangential thread was referring to the UK. Your roommate would
have to be very alert and fit to be able to realise the phone is
ringing and answer it within 400ms :)

With a 20Hz ringing current, that's just eight cycles of AC per ring.
A piece of kit that tries to detect ringing without just leaving it to
finish ringing is likely to suffer from false positives.

Well, the X100P (or at least a clone) is an unreliable piece of junk
anyway, so this doesn't surprise me. Mine has now taken to randomly
answering the line even when there's no inbound call, and has now been
relegated to being just a Zaptel timing source.
