I am sure they extensively use artillery, but if you mean indiscriminate shelling, that's not very efficient in urban combat. The rubble is even easier to defend than normal urban terrain, and unless you completely collapse a building's structure you're unlikely to kill the occupants once they take cover, which they will rush to the moment the first shell lands. Leveling every building completely with artillery would wear our your artillery pieces and chew through your ammo at an unsustainable rate for pretty much any army, but especially for the Israelis, who mostly operate expensive high end artillery IIRC.
