I think it is this one , it's called "The dead end call"

Justice League hotline DPxDC

Jazz paused in her studying and turned her attention to the news she had idelly playing for background noise. She had gotten into the habit ever since Phantom and her parent’s ghost fighting started becoming a regular part of the local broadcast. Though it tore another piece of her heart out every time she saw them shoot phantom and threaten to destroy him molecule by molecule. Now that she knew Phantom was Danny she wondered how they didn’t see.

But that wasn’t what caught her attention today. Instead it was the group of super heroes that had stopped that alien invasion last month. And hadn’t that been interesting. She had been hearing rumors and conspiracies for years about vigilantes fighting crime in other cities around the world, but the video footage from the thwarted invasion was the first time anyone had really seen any of them. Well except for Superman, but he had always been really open about helping people. The fighting had been so heavy the heroes hadn’t the luxury of stealth. And now the eight oddly dressed people were on TV announcing they were forming a group to better help protect the earth’s people.

They had just finished setting up their base and have made a telephone hotline people could call and report any suspected activity of supervillains or mad scientist. The tv then showed several examples from Gotham and Metropolis’ more notable criminals.

As Jazz watched the video montage of heroes taking down different rogues a knot started to form in her stomach at how familiar it all looked. Then suddenly the local news cut the national broadcast to show yet another fight between Phantom and one of the ghosts, with her parents catching up. Shooting and shouting at both the glowing specters. A shot aimed at phantom was dodged and hit the other ghost instead. Danny was quick to suck it into the thermos and flee. The local reporter couldn’t keep up but knew the event was over with how fast Phantom flew away.

The broadcast changed back to national news. At the bottom of the screen the Justice league hotline number was still displayed. Jazz hesitates a moment wondering if this was really the right thing to do, but ultimately begins to dial anyway.

“Hello, Justice League? I think my parents may be mad scientist.”
