SIP 302 Moved Temporarily vs 407 Proxy Authentication Required
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 407 (Proxy Authentication Required) is a 4xx Client 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, 407 means that the client must first authenticate with the proxy. The proxy returns a Proxy-Authenticate header with a challenge.
