SIP 301 Moved Permanently vs 436 Bad Identity-Info
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 436 (Bad Identity-Info) 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, 436 means that the Identity-Info header contains a URI that the server cannot dereference to obtain the signing certificate.
