SIP 182 Queued vs 410 Gone
SIP 182 (Queued) is a 1xx Provisional response, while 410 (Gone) is a 4xx Client Failure 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, 410 means that the requested resource is no longer available at the server and no forwarding address is known. This is expected to be a permanent condition.
