The situation as it appeared itself and passed by itself.
On the detail from the operator, the duration of the call is equal to the sum of the durations of all records. There is no robot or IVR there.
The handset, as I understand it, did not rise and the call was not placed on hold. Can someone suggest how to appeal to an operator with such a problem?
