apid increase in adoption but limited the features that could be delivered. The basics of a handset with at least 10 keys and lighted buttons to indicate the active lines have remained the same, but the trends in the enter- prise handsets over the next 10 years should be dramatically different. Chapter 2: Trends in IP Telephony 15 Desktop Handset Trends The current desktop handset for IP Telephony has a few distinct differences from the older versions. The first major difference is the power of the platform. With the advent of cheaper and faster Digital Signaling Processors (DSP), faster and cheaper memory, and System on Chip (SoC) technologies, the basic handset has a great deal more power today than when it was first introduced. As this trend continues, you should see desktop hand- sets get more and more CPU power. The most advanced desktop handsets today have a full CPU that would be the equivalent to the fastest desktop computers of 1999 with as much memory as most computers in 1999 (1.6 Ghz ATOM chip with 512 MB of RAM). The second change in the desktop phones is in the area of display. The state of the art today is a touch screen combined with a full-color display that enables for full motion video to be displayed. These displays blur the line between a phone and a computer. The next trend in the handset market is to improve acoustics through a combination of higher fidelity headsets and better audio compression techniques. Modern headsets have the capability to support wideband audio. The other trend in headsets is the integration of Bluetooth to support industry-standard headsets. Historically, the headsets included in desk phones have been expensive propriety wireless devices or wired devices that have not been that functional. The biggest trends to date in IP Phones can be summarized as: Higher speed central processors (DSP- or CPU-based) Larger and better screens, including touch-screen capabilities Better audio capabilities Built-in Bluetooth support In the future, the primary trends in desktop IP Tel
