The one big difference I have found isn't about communicating with your team, but that when you are actually at the office you spend a lot more time talking to people not on your team or in your department. People with entirely different backgrounds and working on entirely different projects.
This can lead to new and creative developments and projects that would never happen from simply talking to people on your team. These projects have, at least for me, often been the most fun and challenging (and profitable) project I've been involved in.
