After the caller hangs up, the operator stays on the call and a Call Whisper plays. The Whisper asks for the 4 digit code unique to the operator. If you use Call Ratings as well, the Call Rating Whisper plays after. This code is then shown in the Call Log as the Operator Reference.
The Operator Reference codes are determined and controlled by you, there is no place in the Portal to store these numbers. In the Call Log only the Operator Reference code is shown, not the operator’s name.
This feature is controlled per tracking pool, so it must be turned on for each tracking pool you want to use it on.
