SIP 302 Moved Temporarily vs 433 Anonymity Disallowed
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 433 (Anonymity Disallowed) is a 4xx Client Failure response. 302 indicates that the callee has temporarily moved to a different address. The client should retry the request at the Contact address but continue using the original URI for future requests. In contrast, 433 means that the request has been rejected because the server policy requires caller identification and the request was anonymous.
