             Summary: Mismatched response to outgoing REGISTER request
                 Key: ASTERISK-25020
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25020
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.1.0
            Reporter: Mark Michelson


Internal testing at Digium encountered a situation where some mysterious happenings occurred regarding an outbound REGISTER. The logs show an outbound REGISTER occurring, then receiving a 401 response to the REGISTER. After this, there are a series of incoming REGISTER transactions and outbound OPTIONS transactions. And at the very end, there is an error message showing that the outbound registration failed due to a fatal 404 response being received.

The logs show no such 404 response being received in response to the outbound REGISTER. What's odd, though, is that immediately before the warning is printed, there is a 404 received in response to an outbound OPTIONS request. Based on the limited debugging, the conclusion may be that somehow, the 404 response to the OPTIONS request somehow got treated as a response to a REGISTER.
