SIP 302 Moved Temporarily vs 483 Too Many Hops

SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 483 (Too Many Hops) 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, 483 means that the Max-Forwards header has reached zero, indicating the request has passed through too many proxies.
