Hi Daniel,
If it is the case then the ordering shouldn't be 1,2,3,3 ? but I'm getting 3,1,2,3.
I tried to set $(branch(uri)[-1]) = $null; after the while block , but nothing changed :(
Thanks,
Ali

Hello,
next_gw() is also setting the r-uri, so for the last successful next_gw() you should not call anymore append_branch(). Try to remove the last branch after the while block:
$(branch(uri)[-1]) = $null;
Cheers, Daniel

Hi Daniel,
I'm using this method because I'm having issue with append_branch where last gateway is listed first.
For example if gateways are ordered in LCR_rule_target as 1,2,3 , I'm having them in contact header as : 3,1,2,3
I'm using below code :
if (!load_gws(1, $rU, $fu)) {
sl_send_reply("502", "Unable To lOad GatEwAyS");
exit;}
while(next_gw()){
append_branch(); }
sl_send_reply("302","Moved Temporary");
exit;
}
Any hint regarding the above would be appreciated.
Regards,
Ali

Hello,
the r-uri is added as a Contact address for 3xx replies -- I don't remember if this is some RFC requirement or just an implementation of the sl function for 3xx replies (well, I haven't implemented those function either).
The active branches of the request are added as contact header to the reply. So you can practically use append_branch() as many times as you need and then do sl_send_reply("3xx", ...). You don't need to append headers to replies explicitely.
Cheers, Daniel

Hello,
I'm trying to build new contact header that will be sent from Kamailio as below :
load_gws(1, $rU, $fu);
append_to_reply("Contact:");
while (next_gw())
{
append_to_reply("$ru");
}
append_to_reply("\r\n");
sl_send_reply("300","Multiple Choices");
exit;
yet I'm getting two Contact headers as shown in below SIP message.
How can I remove second contact header (highlighted below in gray)
