SIP 182 Queued vs 607 Unwanted
SIP 182 (Queued) is a 1xx Provisional response, while 607 (Unwanted) is a 6xx Global 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, 607 means that the called party did not want this call from the calling party. This response is used for robocall and spam call blocking.
