Doha is 12 hours ahead of Anchorage
There is no standard 8-to-6 overlap. Someone joins early or late.
Given Doha is 12 hours ahead of Anchorage, the realistic answer is that there's no convenient shared slot during normal business hours. Catch the edges of the day: the last hour for Doha or the first hour for Anchorage is usually the least painful option. Watch the DST gap — when Anchorage changes its clocks and Doha stays the same, this window slides by an hour.
