Enhanced Call Control - One number for all your calls.
You have four phone numbers, but you're still hard to reach. Instead, use one number and don't miss another important call. Forward your calls to simultaneously or sequentially ring your office, cell phone and the softphone on your laptop. You can specify call handling by caller ID too, so you remain reachable for your most important callers. You can set-and-forget, keeping your preferred settings all the time, or change it depending on your travel schedule.
