I have simply used ‘t_check_status’ in the failure_route. This works. But, with a CFNA it doesn’t work : the incoming call is treated by SER (0.9.9). After the timer has expired the call goes to ‘failure_route’ for the first time to setup the CFNA with, finally, an ‘append_branch’. At this moment, the first gateway replies with 5xx and the call never goes to ‘failure_route’. I can match the 5xx within the ‘onreply_route’, but that’s all. So, instead of trying another gateway, the initial incoming calls terminate on the voicemail. Can anyone help me? Hello, Have you loaded the/another failure route for the second time in the CFNA failure route handler?
