I can't login with my softphone using same rewrites. Without rewrites if
client is set to proper setting and my kamailio is used only as proxy, it
works.

I need at least this rewrite:

route[6] {
  subst('/^(From.*sip:)[0-9]+ at xxx.xxx.xxx.20(.*)$/\1xxxx07505 at as.vvn.xxxxx.xx\2/i');
  rewritehostport("as.vvn.xxxxx.xx");
  t_on_failure("6");
  route(5);
}

My target is checking for their domain in From: header. Can I use some
transactional rewrite, which can automatically rewrite this change back?
I tryed to use t_on_reply without success yet.

Is it normal behaviour to check for existence of From header and only allow
target's domain? I need to make a trunk between our voip site and target's,
so I think it's normal, that our domains are different.

Thank you.
