Nick,
Any special reason why your're using port 5061? It's the port for sips
(sip over TLS), so maybe the client doesn't like that? Try 5060, maybe
that helps.
Beside that, can you ensure the client got that response? Any NAT in
between?

I was using 5061 because it's a VM running on the same server, and this
way I was able to filter the traffic when looking at the ngrep output...
I just got a mail from Xlite support they said the problem was probably
this: Mobilia SIP Server.
My server header/signature was confusing the clients, as soon as I
removed it, everything works perfectly... probably I need to learn a bit
more about what can go in headers.
