SIP 301 Moved Permanently vs 580 Precondition Failure
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 580 (Precondition Failure) is a 5xx Server 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, 580 means that the server is unable or unwilling to meet some of the preconditions specified in the request for resource reservation.
