Ask HN: Conference phone/hardware recommendation?

Does anyone have a recommendation for hardware for conference calls? Most of our team is in one location with the occasional remote member or client calling in. We love hipchat, uberconference, hangouts etc. but sometimes we just want that person who's WFH that day to be able to hear what everyone else around the table in the office is saying. We currently use a polycom soundstation2 which means only the two people directly next to the phone are audible to the other side. Any ideas?
