I am talking about calls going thru gateways in any case. How can check wich timer has been hit when I get in the failure route. I user doesn't answer for any reason, I get a 408 in failure route, what if the gateway in between had a problem and didn't anwer at all.
fr_inv_timer hits if proxy has received a provisional reply to invite. you can test that in your failure route if you have set a flag in reply route when provisional reply was received.
