DSS keys are used to monitor other people's lines. This is the preferred option for Manager/Assistant setups, and is similar to a BLF (Busy Lamp Field). Note that whenever a device has a DSS key, it will also have to have a primary line key labelled My Line.
Suppose your extension 19270 is the primary line on your phone, and you have a DSS key of 88667:
- When 19270 is called, the key labelled My Line will flash. Pick up the receiver to take the call
- When 88667 is called, the key labelled 88667 will flash. Press the button to pick up the call
- If someone else with a DSS key of 88667 has picked up the call, the light will be steady
- If the light is not flashing or lit, press 88667 to ring 88667 (it works like a speed dial)
