SIP 302 Moved Temporarily vs 413 Request Entity Too Large
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 413 (Request Entity Too Large) 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, 413 means that the server is refusing to process the request because the message body is larger than the server is willing to accept.
