SIP 302 Moved Temporarily vs 513 Message Too Large
SIP 302 (Moved Temporarily) is a 3xx Redirection response, while 513 (Message Too Large) is a 5xx Server 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, 513 means that the server was unable to process the request since the entire SIP message (not just the body) exceeded the size limit.
