DTS821S is a digital telephone set for Telesis Hybrid IP PBX Business Phone Systems and the X1 for the comfort of the user. DTS821S has numerous dedicated keys for various telephony tasks and personnel settings. It has a large backlighted graphic LCD.

DTS821S is connected and powered by a single pair of wires. The set handles multiple calls simultaneously, such as receiving a new call while keeping another on hold.

Users without need of many quick access keys may choose the DTS821S and get the benefits of the Telesis systems.

A few of easy-to-use functions with the DTS821 are:

  • in idle state:
  • in other states:
    • deflecting calls
    • activating call back
    • holding calls on
    • retrieving calls
    • transferring calls
    • tracing transferred calls (up to 4 calls)
    • activating conference
    • recording the conversation bi-directionally (both calling and called party voices)

Intelligent algorithms within the operating system of the Telesis Hybrid IP PBX Business Phone System and X1 make the firmware upgrade of DTS821S digital sets automatic whenever new features are added in time. Furthermore, since all the user parameters are stored in the system, replacing and / or upgrading a DTS821S digital set does not require any re-programming.
