Hi Carsten,

Thanks for responding. 

1) I basically call a t_suspend for an incoming INVITE and resume it when the call is ready to be patched.

2) I set my fr_timer as 30 seconds as I do not want the caller to wait for a long time to get connected. 

3) So when kamailio responds back with a 408 after 30 seconds, I want to do an http request to let the called party know about the missed call.

Hence I need to get access to variables like $tU when kamailio generates a 408 to send the missed call notification to the right recipient.

Thanks,

- Jayesh

Hi Jayesh,

you should be able to catch this in a regular failure_route(). What do
you want to achieve? Replace the response?

failure_route[myfailure] {
    # Execute, in case we
    # - get a local generated "408"
    # - receive a 5xx or 6xx reply from the proxy.
    if (t_branch_timeout() || t_check_status("[5-6]..")) {
        send_reply("486", "User offline");
        exit;
    }
}

Thanks,
Carsten
