Can anyone please give me a hint how to access the reply reason in failure_route - or is it really not possible to trigger some event on the response _reason_.
 0(704) SIP Reply  (status):
 0(704)  version: <SIP/2.0>
 0(704)  status:  <404>
 0(704)  reason:  <CLIR Inactive>   <----- I want this!
There is a pseudo variable for that, but no function can search the replied reason!
Is it really true, that you can use the reply status only (t_check_status("404"))?
 
Using avpops the pseude variables $rr and $rs are <null> at that moment. Do I miss something?
I'm doing that:
failure_route[3]
{
        if (t_check_status("404") ) {
                avp_printf("$reason", "The reply: $rr, $rs");
log("\n----------------------------------------\n");
avp_print();
log("\n----------------------------------------\n");
        }
}
resulting in:
 0(740) DEBUG:avpops:print_avp: p=0xb6177838, flags=2
 0(740) DEBUG:                  id=<32>
 0(740) DEBUG:                  val_str=<The reply: <null>, <null>>

Any hints welcome.
