Wanting to do some ISN testing from a cell, I set up a PSTN number
that forwards to ISN. I cannot make any guarantees on how long it
will remain up, but if anyone else needs to do any similar testing,
please feel free to try out:

+1 712 432 7935

You'll be prompted for the ISN number, followed by #. After entering
the number and # it will repeat the number back to you, to the NAPTR
lookup and then connect to the first (ordered) E2U+sip URL returned.

The box it's on is good for a few simultaneous calls, but not too many.


(ObDisclaimer: Yes, I could potentially get a kickback of a few bucks
if that number gets significant use. I intend to
donate anything significant to one or more worthy
free/libre projects.)
