Hello,
there is no parameter to disable adding new r-uri as a contact, I suggested to be added.
Meanwhile I looked at the code and there could be an option to get it work.
Append a branch after each next_gw() and before sending reply, do "revert_uri();" (ie., instead of dropping last branch do revert_uri()).
Cheers, Daniel

Hi Daniel,
I tried the following mod param : modparam("sl", "bind_tm", 0), which is the only boolean param in sl module , but unfortunately still the same
How could I shift the URIs ?
Thanks,
Ali

Hello,
the last address from next_gw() becaomes the last r-uri and that is added as first contact. You will have to shift the URIs. Maybe the simplest way would be to disable adding r-uri as contact in 3xx via a mod param in sl module.
Also, if you use 4.3, might worth looking at rtjson module, you can build a json holding the destination addresses in the order you want and the push them to r-uri and branches.

Hi,
I tried to not calling append_branch() when last successful next_gw() using below code :
$var(z)=0;
$var(a)=0;
if (!load_gws(1, $rU, $fu))
{
sl_send_reply("502", "Unable To lOad GatEwAyS");
exit; }
while(next_gw()) $var(z) = $var(z) +1;
xlog("L_INFO", "number of gateways : $var(z)\n");
load_gws(1, $rU, $fu);
while (next_gw()){
xlog("L_INFO", "gateway is : $ru\n");
$var(a)=$var(a)+1;
if($var(a)!=$var(z))append_branch();
}
In this case I'm getting in contact headers the following gateways : 3,1,2

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.

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)
