Is an interphone the same thing as an intercom? If so and it has a brand name you can see, you might be able to find operational instructions on the internet.
But I'm guessing it's a simple device hardwired into the building, and can't be muted unless you open the box and disconnect a wire leading to the speaker. If you don't see any screws (on the outside of the box) then it's possible the box can simply be popped off by pulling on it, but be careful not to break anything if it doesn't want to come off.
Is there an apartment manager you can ask about this? Or by 'apartment' do you mean temporary lodging, such as a hotel or motel? If so there should still be someone you can ask... and it's possible (if not likely) that there's nothing you can do about this problem without getting yourself into trouble with the owner.
edit: I was outside for a moment and looked at the box (through remote viewing) and it might be a good idea to first try pulling up at an angle. There might be a hinge at the top (on the inside) and you don't want to be pulling on the hinge itself. If the box pops loose at the bottom then you can either swing the box up or remove it from the hinge...
Goosed by a Duck is gonna have a cow if this remote viewing thing works, so I hope that's how the box is supposed to come off.
