The external power supply block is not required in that case. For optimum ease of use and complete user mobility the elmeg IP-S290plus supports wireless DECT Headsets having a DSHG interface as well as “classic” wired headsets. Two programmable buttons, labeled „Headset on/off“ and „Auto-Answer“, on the telephone set allow for headset control with utmost ease. Flexible, fully networked office environments primarily benefit from the device’s features like Open Listening, Hands Free Calling, VIP Dialing and its programmable function keys, which enable a variety of new functions such as Voice Mail, Call Rerouting or Direct Dial button assignment capability. All function keys now have bicolor LEDs, allowing the user to spot the enabled status of the second-layer function keys instantly.
