SIP 302 Moved Temporarily vs 437 Unsupported Certificate
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 437 (Unsupported Certificate) 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, 437 means that the server was unable to validate the certificate referenced by the Identity-Info header. The certificate may be self-signed or from an untrusted CA.
