SIP 302 Moved Temporarily vs 436 Bad Identity-Info
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 436 (Bad Identity-Info) 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, 436 means that the Identity-Info header contains a URI that the server cannot dereference to obtain the signing certificate.
