Why each option

SIP 5xx series responses indicate server-side errors, with common examples being Server Timeout (504), Service Unavailable (503), and Version Not Supported (505), all of which can lead to call disconnects.

AServer timeoutCorrect

504 Server Timeout - The server did not receive a timely response from an external server it needed to access to complete the request.

BBad request

400 Bad Request - This is a 4xx client error, indicating the server cannot process the request due to malformed syntax.

CTemporarily unavailable

480 Temporarily Unavailable - This is a 4xx client error, indicating the called party is temporarily unavailable.

DService unavailableCorrect

503 Service Unavailable - The server is temporarily unable to handle the request due to temporary overloading or maintenance of the server.

EForbidden

403 Forbidden - This is a 4xx client error, meaning the server understood the request but refuses to fulfill it due to authorization or policy issues.

FVersion not supportedCorrect

505 Version Not Supported - The server does not support the SIP protocol version specified in the request.
