I thought this article might have a little more info on the phone calls. Not really but there are some interesting quotes from Gazans.
Phone Call Tells Gazans to Get Out; Missiles Hit Minutes Later

“Look, I mean, everyone has the right to defend himself. They are saying that they’re defending their selves. Of what? Of rockets. They have no missiles in them. It’s an empty rocket. It’s just a kind of tube kind of going and doing nothing. But it’s our way of defense. We have nothing,” Matar said.

“I have only one kid, a little girl, and I want her to live in peace. I want her to live in Palestine. We have the right to defense ourselves. No one wants war, no one…But what kind of peace we need, that is the question,” he said.

A Palestinian man at a Gaza hospital today was more blunt as dead bodies were brought out for funerals. The bodies included some of the nine members of the Daloo family who died Sunday when the Israeli missile destroyed the building in which they had been.

When asked whether he thought the toll on civilians, particularly children, was too high and Hamas and its allies should stop firing rockets at Israel, he replied that the victims included a woman in her 70s and a 4-year-old child.

“All the Israeli media said that there are fighters inside the house, but we are from the family. We’re denying totally that there is a fighter inside the house that was bombarded,” he said.

“And we ask all the groups to retaliate for these massacres and we believe now we shouldn’t talk about ceasefire at all,” he said.

It’s really hard to understand the logic of firing empty missiles but the public seem to like the idea.
