[OpenSIPS-Users] Midregistrar handle failed registrations

[Ben Newlin]

John,

The status of the response is exposed in several places, depending on your configuration. It can be accessed vis $rs [1], but since failure_route is processing the request you will need to specify the reply context [2], so $(<reply>rs). But if you are using the TM module then you can just use $T_reply_code [3].

The initial challenge for auth (401/407) will trigger the failure route, so every request will end up in failure route at least once if they are all challenged. But if authentication is successful and 2xx is returned it will not trigger the failure route a second time. The only place to see the 2xx status code is in a reply route.

I have tried using t_on_failure + failure_route but every registration
ends up in the failure_route branch regardless of whether the
authentication was successful or not.

Does anyone know how I can capture the response returned from the main
registrar please to know in script whether the register was
authenticated or not?
