Hi Tiana,
Could you respond privately with a HTTP request that shows this behaviour?
May be the behaviour of this report changed recently due to another change
on our servers. If that's the case, I'll get the documentation updated.

On Wednesday,
I just tried fetching data from the `CALL_METRICS_CALL_DETAILS_REPORT` using
the *DURING* clause and it seems to work, I only get calls returned from
within the date range, but the documentation still says it shouldn't work
