SIP 301 Moved Permanently vs 470 Consent Needed
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 470 (Consent Needed) 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, 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).
