Ok, there are 2 separate issues here:
(1) should SIPConnect 1.1 provide a method to pragmatically update
where the SP-SSE should send requests for a given URI, for working on
dynamic IP addresses?
(2) should SIPConnect 1.1 work behind NAT?
Which of those do people actually care about? If i'm the only person
who wants (1) to work with SIPConnect 1.1, then i'll stfu on the
subject - however, given 3 large UK SPs use (1) with ~ 60%  of
their "sip trunk" customers, it seems pretty important from where I
1 - "quick ballpark figure, please" from the other 2 gave me that
answer, so it's not by any means scientific!
