SIP 301 Moved Permanently vs 438 Invalid Identity Header
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 438 (Invalid Identity Header) 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, 438 means that the server obtained the certificate from the Identity-Info header but the signature in the Identity header is invalid.
