Hi

First of all, do not onreply, for 3xx is used failure_route, which must be applied before
rewritehost("x.x.x.x");
t_relay();

Approximately like this
t_on_failure("FAIL");
rewritehost("x.x.x.x");
t_relay();

In order not to forward the response 302 to the user, use the function t_drop_replies () ;

Approximately like this

failure_route[FAIL]
{
    if (t_check_status("302") )
    {
      t_drop_replies();
      .....
     }
 }

How do I send ACK to (B) to finish this redirect ?
ACK kamailio should automatically send itself.

Then I want a new relay to the host. How would I do it ?
After the function t_drop_replies (); you can forward the original or changed request to where you want it to be, by analogy how the first one was processed.

Hi

I am aiming to do the following

User calls to Kamailio Switch (A)
Switch (A) calls to Kamailio redirect server (B)..
(B) runs script to determine route
(B) sends Stateless 300 redirect reply to (A).
(A) sends ACK to (B).
(A) send user call to another host (extracted from header variable from redirect reply)



(A) call to (B)
rewritehost("x.x.x.x");
t_relay();


(A) On receipt of the 300 response I do not want this redirect to go back to the user.

onreply_route {
        if (t_check_status("3[0-9][0-9]")) {
// How do I send ACK to (B) to finish this redirect ?
// Then I want a new relay to the host. How would I do it ?
        }
}
