SIP 301 Moved Permanently vs 413 Request Entity Too Large
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 413 (Request Entity Too Large) is a 4xx Client Failure response. 301 indicates that the user can no longer be found at the address in the Request-URI. The client should direct future requests to the new address in the Contact header. 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.
