SIP 200 OK vs 302 Moved Temporarily
SIP 200 (OK) is a 2xx Success response, while 302 (Moved Temporarily) is a 3xx Redirection response. 200 indicates that the request has succeeded. For INVITE, the call has been answered. For other methods, the action has been completed successfully. In contrast, 302 means 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.
