SIP 302 Moved Temporarily vs 428 Use Identity Header
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 428 (Use Identity Header) 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, 428 means that the server requires an Identity header to verify the caller's identity but it was not included in the request.
