In addition to the hardware, the software was integrated with the process so that users could get rich caller information such as their communications history with the caller (for example, via a pop-up window on-screen with all the voicemail and e-mail history from that person), based on the caller ID. While some of the elements themselves weren't new, "Athens" was unique in bringing together the software, hardware, peripherals and the design to pull everything together.
