In an office environment you can walk around the floor, pop into other people's convos or meetings, learn news and rumors from water cooler conversations. You can do this organically when you see people having a break.
In a remote environment you have no idea if you're interrupting someone when you give them a call, so you need a proper reason to call someone. People discuss things in closed conference calls, chat rooms and email chains, so if they don't invite you you will never learn about any opportunities yourself.
