Call Bets (or Announced Bets) are special roulette wagers that cover specific sections of the wheel. They include Voisins du Zéro, Tiers du Cylindre, Orphelins, and others. They're called "call bets" because players traditionally announce them verbally rather than placing chips themselves.
Voisins du Zéro ("Neighbors of Zero") covers 17 numbers near zero on the wheel (22-25). It requires 9 chips: 2 on 0/2/3 trio, and splits on 4/7, 12/15, 18/21, 19/22, 32/35, plus a corner on 25/26/28/29. It covers 45.9% of the wheel.
Tiers du Cylindre ("Thirds of the Wheel") covers 12 numbers opposite zero on the wheel. It requires 6 chips placed on six splits: 5/8, 10/11, 13/16, 23/24, 27/30, and 33/36. It covers about 32.4% of the wheel.
Orphelins ("Orphans") covers the 8 numbers not included in Voisins or Tiers. These numbers appear in two slices of the wheel. It requires 5 chips: 1 straight on number 1, and splits on 6/9, 14/17, 17/20, and 31/34. Note that 17 is covered twice.
