SIP 182 Queued vs 413 Request Entity Too Large
SIP 182 (Queued) is a 1xx Provisional response, while 413 (Request Entity Too Large) 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, 413 means that the server is refusing to process the request because the message body is larger than the server is willing to accept.
