There's 8 of us in our programmer section; people take Google Hangouts and their phone calls within the section. It takes a few minutes to walk out to a private phone area and the other conference room's door doesn't close properly so you can't block off your noise. So what we do is just wear headphones and try our best to ignore other people's conversations. Which is a problem because all the other office workers are usually so quiet that it's like a library in the office.
