SIP 182 Queued vs 302 Moved Temporarily
SIP 182 (Queued) is a 1xx Provisional response, while 302 (Moved Temporarily) is a 3xx Redirection response. 182 indicates that the called party is temporarily unavailable but the server has decided to queue the call rather than reject it. The call will be attempted when the callee becomes available. 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.
