SIP 301 Moved Permanently vs 430 Flow Failed
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 430 (Flow Failed) 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, 430 means that the specific flow to a user agent has failed but other flows may succeed. Used with SIP outbound (RFC 5626).
