SIP 301 Moved Permanently vs 437 Unsupported Certificate
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 437 (Unsupported Certificate) 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, 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.
