SIP 301 Moved Permanently vs 433 Anonymity Disallowed
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 433 (Anonymity Disallowed) is a 4xx Client Failure response. 301 indicates that the user can no longer be found at the address in the Request-URI. The client should direct future requests to the new address in the Contact header. In contrast, 433 means that the request has been rejected because the server policy requires caller identification and the request was anonymous.
