SIP 301 Moved Permanently vs 408 Request Timeout
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 408 (Request Timeout) 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, 408 means that the server could not produce a response within a suitable time. The client may repeat the request without modifications at any later time.
