elmeg IP-S290plus

The IP-S290plus IP system telephone (central system telephone book, busy light feature, team/line keys, etc.) is used with the hybird and ICT (VoVPN module required) systems. The IP-S290plus supports PoE and wireless headsets.

Product description

The IP systems telephone and the VoIP-VPN Gateway module make the convenient elmeg system telephony available in IP networks. As an interface variant of the elmeg CS290, the elmeg IP-S290plus supports all system features at the ICT systems, such as alternation between lines, call transfer, 3-party conferences, team functions, line keys, access to the systems-internal phone book and many more.

As the successor to the elmeg IP-S290, the elmeg IP-S290plus comes with the following extra features: It supports Power over Ethernet (PoE), which means that: if the network or the upstream switch provides PoE power, the device is automatically powered through its Ethernet port. 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.
