You have selected hour-level metrics, which means you need at least having 1 * 60 calls in this hour, you could have 1 cpm.

[cswjd]

In this way, 59 calls occurred in one hour, and the cpm data will be displayed as 0. I think it is unreasonable, because it is the fact that calls occurred in this hour.

[wu-sheng]

If you take a look at minutes level, it is there. We never said it is traffic, if you wants purely calls, you should learn OAL and UI custom setting.
