SIP 182 Queued vs 433 Anonymity Disallowed
SIP 182 (Queued) is a 1xx Provisional response, while 433 (Anonymity Disallowed) is a 4xx Client Failure response. 182 indicates that the called party is temporarily unavailable but the server has decided to queue the call rather than reject it. The call will be attempted when the callee becomes available. In contrast, 433 means that the request has been rejected because the server policy requires caller identification and the request was anonymous.
