Noting that the order of gateways above is correct , but in contact field
I'm getting : sip:9612 at 192.168.26.8 , sip:9612 at C001 , sip:9612 at 192.168.26.1
, sip:9612 at 192.168.26.6 , sip:9612 at 192.168.26.8
Below is full code I'm using:
if (is_method("INVITE"))
{
if (!load_gws(1, $rU, $fu))
{
sl_send_reply("502", "Unable To lOad GatEwAyS");
exit;
}
while (next_gw())
{
append_branch();
}
xlog("L_INFO", "Before assigning $null");
$var(i)=0;
while($var(i)<$branch(count))
{
xlog("L_INFO", "branch uri[$var(i)]: $(branch(uri)[$var(i)])\n");
$var(i) = $var(i) + 1;
}
$(branch(uri)[-1]) = $null;
xlog("L_INFO", "After assigning $null");
$var(i)=0;
while($var(i)<$branch(count))
{
xlog("L_INFO", "branch uri[$var(i)]: $(branch(uri)[$var(i)])\n");
$var(i) = $var(i) + 1;
}
sl_send_reply("300","Multiple Choices");
exit;
}

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 :(
Are you still getting all branches? Isn't the last one removed? Can you
print branches before and after assiging $null? you can use:
$var(i)=0;
while($var(i)<$branch(count))
{
xlog("branch uri[$var(i)]: $(branch(uri)[$var(i)])\n");
$var(i) = $var(i) + 1;
}
Cheers,
Daniel

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;

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)
