Why a call was rejected, or a message was not sent

Why a call was rejected, or a message was not sent. We no longer answer a call just to say that the line cannot take it — answering costs call time — so the reason is recorded here instead. "reason" is a stable code you can compare on; the human-readable explanation lives in the dashboard. Filter with "channel" (opkald, sms) and "reason", and page with "before" (an ISO timestamp) rather than a page number, because the log gains new rows continuously.
