Even when working in office, when I have questions, I always ping my colleagues on IM first, instead of directly walking to their desk or shouting at them.

It's respectful and could be turned into a policy.

Not really, also what kind of office setup you have where you don't sit next to your colleagues? Ambient interruptions also are a thing

Yes we're next to each other, but if the person has his headphones on I don't want to disturb him so I write first a message.
