SIP 301 Moved Permanently vs 414 Request-URI Too Long
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 414 (Request-URI Too Long) 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, 414 means that the server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
