[SR-Users] 302 Handling issue in failure route
Hello All
I am handling 302 response in the failure route and when receiving 302
response in kamailio, it's not going into the failure route , kamailio just
executing the onreply route when 302 response are received.
A few days ago the same code with failure route worked but now it does not.
i dont know why kamailio is not executing a failure route from where we can
redirect calls to another server.
code snippet
route[RELAY]{
t_on_reply("MANAGE_REPLY");
t_on_failure("MANAGE_FAILURE");
t_on_branch("MANAGE_BRANCH");
if (!t_relay()) {
sl_reply_error();
}
exit;
}
failure_route[MANAGE_FAILURE] {
if (t_is_canceled()) {
exit;
}
if (t_check_status("302")){
get_redirects("*");
$ru= $T_rpl($sel(contact.uri));
route(RELAY);
}
}
kamailio version : 5.6.4
Please suggest if I am doing anything wrong.

[SR-Users] Re: Recover call in ringing state
Hello Henning Thanks for Response, When Remote Server goes down in Ringing Call state we will not get any Negative Response from remote server and we should not wait for transaction timeout because its to 1-2 min so in this case there is anything that we found Remote server is down and we can check INVITE transaction failover and we generate INVITE using that same transaction. Using the Dispatcher event route we will get if any of the remote servers are down but how we can get a call transaction is failed and can generate a call.

[SR-Users] Recover call in ringing state
Hello All I have below setup : SBC -> kamailio -> Media server(remote) -> web-client Call comes from sbc to kamilio and it relays to Remote server to end user, In Ringing state if remote server goes down then in kamailio there is any way to Recover that ringing call like we can generate new invite for other Remote server which is active state, for relaying call i am using dispatcher module.. I tried with tm.cancel RPC command but it works only if the remote server is running , when I crash the remote server at that time tm.cancel is not generating cancel to remote server.

As you can see Contact header is gone but
sip:1...@172.xx.xx.x:39931;transport=UDP

Any suggestion will be highly appreciated.
