About a year and a half ago when I was running a couple of x100p's
there was an issue associated with disconnecting the pstn line from
the card. If I recall correctly, if the pstn line was removed for
more then a second or so (a couple of times), the card would go into
some unknown state and it had to be restarted. The comments/fix at the
time were oriented around "don't do that" instead of fixing the code
to recognizing it.

I don't have a clue whether that is still an issue with the x100p
code or not.

You might try using a regular old voltmeter on the tip/ring of the
line going to the Toshiba and watch what happens at the end of a
VM call. It is possible the Toshiba is opening/disconnecting the
line for some rather lengthy period (disconnect supervision).
