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.

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
