Best overlap: 8:00 AM to 2:00 PM in Paris is 12:00 PM to 6:00 PM in Islamabad.
For a call that suits both sides, look at 8:00 AM to 2:00 PM in Paris / 12:00 PM to 6:00 PM in Islamabad. Despite the 4-hour difference, a 6-hour overlap keeps things simple and gives both teams breathing room. Remember that Paris shifts for daylight saving and Islamabad doesn't, so recalculate the overlap after each clock change.
