I am having trouble setting up a failure route to roll over to another on failure. I have failure_route[1] set up to catch 302 redirects and act accordingly. If no redirect is detected then the INVITE should roll to failure route 2, as per the line that says t_on_failure("2");. This is however not what occurs. When an INVITE comes in, and hits failure_route[1] I can see in /var/log/messages that it hit that route, however it never gets to failure_route[2] even though there is no 302, instead the 408 is sent to my sip provider, they ack it, and the call is dropped. Any help is as always greatly appreciated.
