Looks like you are not familiar with SER functions. Suggest you read the document in onsip.org.
Your routing logic direct the request to route(2) when user cannot be found in location table. In route(2), you send a 404 reply and then "break". This tells SER to stop processing further down the logic.
First, don't send 404 if you are going to try alternate path. The UAC may terminate the transaction. Even if your PSTN answer, the UAC will not accept it.
Second, just forward the call to PSTN.
Third, SER will only run failure_route with reply. In your case, you don't even send the request. So, SER will never goes into failure_route.
Hope that make sense to you.

Hi all,
I have a problem with sending a call to PSTN gateway when user is offline. I always get "404 Not found" what is normal because user is not in location database, but I don't understand why failure_route[1] doesn't work. Below is my ser.cfg so if someone could help.
I'm using ser 0.9.3.
Any help would be appreciated.
Thanks
