SIP 301 Moved Permanently vs 608 Rejected
SIP 301 (Moved Permanently) is a 3xx Redirection response, while 608 (Rejected) is a 6xx Global 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, 608 means that an intermediary machine or process rejected the call attempt. Similar to 607 but the rejection comes from the network rather than the end user.
