ACD (Automated Call Distribution)
Commonly used in Call Centers. The device that automatically answers all incoming calls, sends the calls to the first available agent, or, if all agents are busy, plays a recorded message and places the call into a queue until an agent becomes available.

DECT (Digital Enhanced Cordless Telecommunications)
A digital wireless telephone technology that is expected to make cordless phones much more common in both businesses and homes in the future. Formerly called the Digital European Cordless Telecommunications standard because it was developed by European companies, DECT's present name reflects its global acceptance. Like another important wireless standard, Global System for Mobile communication (GSM), DECT uses time division multiple access (TDMA) to transmit radio signals to phones. Whereas GSM is optimized for mobile travel over large areas, DECT is designed especially for a smaller area with a large number of users, such as in cities and corporate complexes. A user can have a telephone equipped for both GSM and DECT (this is known as a dual-mode phone) and they can operate seamlessly.

Noise Cancelling
A technology used in headsets to reduce the ambient noise that a sensative headset microphone would otherwise pick up. You must pick a headset that specifically states NC or Noise Cancelling.
