SIP 302 Moved Temporarily vs 414 Request-URI Too Long
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 414 (Request-URI Too Long) 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, 414 means that the server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
