SIP 182 Queued vs 470 Consent Needed
SIP 182 (Queued) is a 1xx Provisional response, while 470 (Consent Needed) 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, 470 means that the request cannot be fulfilled because the source has not been granted consent by the recipient. Used in consent-based communications (RFC 5360).
