SIP 302 Moved Temporarily vs 580 Precondition Failure
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 580 (Precondition Failure) is a 5xx Server Failure response. 302 indicates that the callee has temporarily moved to a different address. The client should retry the request at the Contact address but continue using the original URI for future requests. In contrast, 580 means that the server is unable or unwilling to meet some of the preconditions specified in the request for resource reservation.
