Hi Cameron,
that's a side effect of how openser deals with changes on the sip
messages. instead of keep re-generating the message buffer after each
change, openser keeps the original received buffer and the changes are
stored as lumps - they will be applied only when the message is to be
sent out.
all parsing functions (including ones used by pseudo-variables) use the
original buffer, so the changes are not visible.
regards,

I have the following code in openser.cfg
if (client_nat_test("3")) {
#IP address in contact is private IP
#Via is different to address client has contacted us from
#If so then setflag7 to indicate that sender is behind NAT
xlog("client nat test 3 returned true for r-uri <$ru> in
route 3 so will setflag7");
setflag(7);
xlog("contact before update <$ct>");
xlog("via before update <$hdr(via)>");
force_rport();
#Rewrite Contact: header to contain Sip client's public
IP:port
fix_nated_contact();
xlog("contact is now <$ct>");
xlog("via is now <$hdr(via)>");
};
However the value returned by $ct is the same before and after
fix_nated_contact(). Is that because I'm doing something wrong, or
because
I've misunderstood fix_nated_contact or because the $ct variable
doesn't get
updated by fix_nated_contact? If the latter, how can I find out the
result
of fix_nated_contact? The same applies to force_rport and the via
details.
Any advice appreciated.
Regards
Cameron
