This reminds me of #CALLBRUSSELS, a Brussels tourism initiative wherein anyone could call public phones throughout Brussels via https://call.brussels and chat about anything. There were live video feeds as well. IIRC this was in January, right around the time Trump and others were making negative comments, so it was meant to dispel concerns about safety in the city.
Here's an article discussing it in detail: http://www.ibtimes.com/callbrussels-new-tourism-initiative-d...
There's also some video content: https://www.youtube.com/watch?v=eRnybwEvQsU
