Hi Jerry,
about your last issue, you have to include RAck in your PRACK manually.
Quoting the answer I got from Pekka back when I was facing problems with
PRACK:
You need the response sequence number (RSeq) from the 180 response in

Regarding RSeq, as you can also see in the quote above, it's not supposed to
be present in PRACK, but in the 18X which you're PRACKing.
