Here is another SIP trace from Kamailio to Asterisk (localhost) - both are
on the same machine, and still get it to respond to Invite (getting
timeouts).
In asterisk logs i did not find anything.
the output sysctl is this:
net.ipv4.ip_forward = 1
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0

I tried with the example bellow, and it's
forwarding the invite, but, i
get request timeout, maybe i need to rewrite some contact headers?
