SIP 182 Queued vs 414 Request-URI Too Long
SIP 182 (Queued) is a 1xx Provisional response, while 414 (Request-URI Too Long) 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, 414 means that the server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
