Snom 870

Snom 870 SIP based 12-line IP phone


The snom 870 VoIP telephone is our latest innovation for all modern people who need sophisticated future oriented technology combined with highest user friendliness. The large high-resolution TFT color display is
not only larger than the one of its little brother snom 821, but it also offers an advancement in technical innovation. This newly developed touch screen has a unique intuitive user interface. Thus the snom 870 enables the user to easily handle even complex applications like call swapping, or establishment of conference calls for five participants via simple drag and drop.

The well-arranged address book ensures that each caller can be quickly identifi ed. It offers room for additional information such as company affi liation, e-mail address and much more. The control elements on the display are designed for active call handling so that the right contact is selected even in multiple call scenarios.

The audio quality of the snom 870 matches the high standards that snom customers have come to expect: wideband audio with silence suppression and voice activity detection. The integrated XML mini browser provides a wide range of additional applications. Whether it is the control of an external USB monitoring camera or accessing the most important stock exchange data; the snom 870 offers a lot of room for extras.

No matter where the snom 870 is used, it is prepared for anything: conventional power supply via wall socket, Power over Ethernet (PoE), or WLAN through USB; the snom 870 adapts to any working environment.A secure connection via VPN, TLS
and SRTP, which prevents the recording of data, completes the picture.

Already familiar from the snom 821 the dual 33° or 55° angle footstand,made of sturdy metal, makes all control elements easily visible and accessible.

With the snom 870 the user gets comfortable access to numerous functions that are very rarely offered in such abundance and convenience by any other device.
