ok, good. The invalid SIP contact is generated by the stack when it is
waiting for a valid contact from the registrar (it notices that it's
behind a NAT, so using the local IP address as contact won't work
anyways).
But if the Asterisk is in the same network addressing domain, then this
could be a bug (we shouldn't put the invalid-contact to the headers if
there is no NAT between us and a registar). And based on the log, this
would seem to be the case (192.168.0.85 is Asterisk's IP, and .90 is the
client IP)...?
The SIP contact management is generally a bit tricky area. Basicly, in
presence of NATs, there is no reliable, standard mechanism for a client to
figure out the correct public IP:port to put to the SIP contact header,
and be certain that everyone can reach it. The standards-based solution is
the IETF sip-outbound mechanism, but the spec is unfortunately not yet
ready. Sofia-SIP already has some code for sip-outbound, and so you also
get the strange looking SIP contacts in REGISTER messages...

Hmm, weird... do you do anything between the 'r' and 'k' commands and
the segfaults.... i.e. does sofsip_cli just sit there for a few secs and
then segfaults? :o
I'd be very interested in seeing a gdb backtrace ('gdb sofsip_cli'->
'gdb> r sip:[EMAIL PROTECTED] --contact="sip:*:5060;transport=udp"' ->
'gdb> bt' after the segfault has happened).
