The rolling ASA for a split is the average call answer time, as specified by the time interval that starts when call processing attempts termination to a split, and ends when the call is answered in that split. The measured interval includes both time in queue and ringing time at the agent station.

If the call is answered in another split or the call is abandoned by the caller, rolling ASA is not recorded for the call. If a call flows into a split from another split, the time queued and ring time for the previous split are not included. If a call is queued in multiple splits, only the rolling ASA for the split in which the call is answered is measured.
