Re: stir/shaken integration with clearip redirect method

Since the redirect response is 3xx+, you should catch it in a failure_route[], which is armed with t_on_failure(). 

In the failure_route, you can check if the failure_route was invoked because of a timeout with if(t_branch_timeout()), and if it was not, extract the reply code with $T_rpl($rs).

Then, you modify the R-URI ($ru) to proceed to the original destination and call t_relay() again.

I've got the basic connection to clearip using t_relay_to_tcp for testing, but I'm struggling with the checks and timeouts. I have call progress past the initial request where I need to wait for a response. Should I put the clearip invite in its own route block use return? Has anyone successfully integrated the redirect method with kamailio to clearip and can give me some example route checks in the kamailio configs?
