SIP 302 Moved Temporarily vs 408 Request Timeout
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 408 (Request Timeout) 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, 408 means that the server could not produce a response within a suitable time. The client may repeat the request without modifications at any later time.
