For a call that suits both sides, look at 9:00 AM to 6:00 PM in Johannesburg / 8:00 AM to 5:00 PM in Lisbon. With 9 hours of daily overlap, these two cities are an easy pairing; almost any reasonable hour works. These times hold for most of the year, but Lisbon's daylight saving (which Johannesburg doesn't use) shifts them by an hour twice annually.
