[OpenSER-Users] Status code 408 returned by OpenSER when fr_timer expires; should it be 504?
Hello everybody,
I noticed that OpenSER replies with status code "408 Request Timeout" when the fr_timer (tm module) expires. I am wondering if the response code "504 Server Timeout" would be more appropriate in this case. The status code 408 means that "the server could not produce a response, e.g., a user location, within the time indicated in the Expires request-header field. The client MAY repeat the request without modifications at any later time."; and the status code 504 means "the server did not receive a timely response from an external server it accessed in attempting to process the request." It sounds to me that the description of the status code 504 better describes what happens in OpenSER when the fr_timer expires. Any comments? I am using OpenSER 1.2.x.
Best regards, Anatoly Pidruchny.

What if there is a 180 ringing response from the upstream server, but no 200 OK within fr_timeout. Is this a "timely response"?
Further, usually 5xx are server internal errors. Thus, If an upstream timeout is triggered, IMO this is not a server error.

Hello, Klaus,

Hello everybody,

Well, for fr_timer, if there is any 1xx response from the upstream server then fr_timer is deactivated and fr_inv_timer is activated. Then fr_inv_timer is expecting the final response from the upstream server, for example, 200 OK. If it is not getting a final response, then I think yes, it is not getting a "timely response".
Further, usually 5xx are server internal errors. Thus, If an upstream timeout is triggered, IMO this is not a server error.
Well, 4xx are usually client errors. IMHO, when a fr_timer or fr_inv_timer expires in OpenSER, it is kind of more a server internal error, then a client error. After all, the client sent a perfectly valid request. So, the server should take the blame on itself rather then tell the client "you know what, you are wrong, not me".
