SIP 182 Queued vs 608 Rejected
SIP 182 (Queued) is a 1xx Provisional response, while 608 (Rejected) 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, 608 means that an intermediary machine or process rejected the call attempt. Similar to 607 but the rejection comes from the network rather than the end user.
