Hi

 

Relevent section of the config similiar to below.

 

Incoming invite is sent to a redirect server, 300 reply is sent back.

failure_route catches the '300' applies t_drop_replies(); and creates a new invite

to host NEW_ADDRESS.

 

The issue I am facing - at this point when a CANCEL is received a '200' is sent back to the requester however it does get notified to the current 

invite which remains processing

 

...

 

if (is_method("CANCEL")) {

    if (t_check_trans()) {

            t_relay();

    }

    exit;

 

...

 

failure_route[FAIL]

{

    if (t_check_status("300")) {

        t_drop_replies();

        rewritehost(NEW_ADDRESS);

        t_relay();

     }

 }
