Hi tbarlo
Welcome to the Community.
Is it possible that a call was missed by the agent but answered by another?
'No Answer from User (user alerted)' indicates that the called party has been alerted but did not respond within a prescribed period of time. While a missed ring attempt occurs when an agent receives a call from queue which is not answered (typically ignored or declined) before the defined Connect Timeout. A ring attempt does not count as missed in a Ring All strategy if another agent answers a call on the same dispatch.
