[sr-dev] tcp problems exists also in older version of sr

[Juha Heinanen]

i thought that tcp problem (using wrong ip address) appeared only in
latest sr code, but now i saw it also in older version.

to repeat, register twinkle using tcp from behind nat.  call twinkle
from another sip phone that is using udp.  twinkle receives 200 ok, but
never the ack.  sr cannot forward ack to twinkle and reports:

Oct 30 10:36:56 localhost /usr/sbin/sip-proxy[3911]: WARNING: <core> [tcp_main.c:1200]: WARNING: tcp_do_connect 192.168.0.169:5074: could not find corresponding listening socket for 192.X.Y.2, using default... 
Oct 30 10:36:57 localhost /usr/sbin/sip-proxy[3924]: INFO: Routing in-dialog BYE from <sip:foo.bar at bar.com> to <sip:jh_bar_com at 192.168.0.169:5074;transport=tcp>Oct 30 10:37:01 localhost /usr/sbin/sip-proxy[4023]: ERROR: <core> [tcp_main.c:3747]: connect 192.168.0.169:5074 failed (timeout)  

where 192.X.Y.2 is NONE of the addresses sr is listening at, but ip of
eth0 interface.

this is a very serious show stopper.
