The snom 870 VoIP telephone is our latest innovation for all modern people with high demands for future-orientated technology combined with user friendliness. The large high resolution TFT colour display is not only larger than the one og its little brother Snom 820, it also offers an advancement in technical innovation. This display is a completely newly designed touch screen with unique, intuitive user interface. Thus the snom 870 enables the user to easily handle even complex applications like swapping of calls, or establishment of conference calls for three participants via simple "drag and drop"

That is the reason why we call the new snom VoIP phone series:

The 8 Experience

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

The audio quality on snom 870 matches the high standard that snom customers have come to expect: wide-band audio with silence suppression and voice activity detection. The integrated XML mini browser in snom 870 also provides a wide range of additional applictions. Whether it be the control of an external usb monitoring camera or to access the most important stock exchange data, the snom 870 offers a great deal of space for extras.
 
No matter where the snom 870 is used, it is ready for every scenario. Normal power supply via wall socket, Power over Ethernet (PoE) or WLAN through USB; the snom 870 fits in each working environment. A secure sonnection via VPN, TLS and SRTP, which prevents the recording of data completes the picture.
 
The dual 33° or 55° angle footstand, made of sturdy metal, makes all control elements easily visible and accessible, just like the snom 820.
 
Moreover, the snom 870 offers all conveniences snom customers have come to expect from us. As security is one of the main requests in our times snom always assumed this responsibility in a very serious way. So features like secure VPN, TLS and SRTP are an integral part of the 870s firmware. To make sure that the data of our customers is secure and to inhibit to hack and copy data is one of our goals we always want to archieve.
 
But the snom 870 also offers a wide range of functions particularly relevant to the business world, like three-party conferencing, polyphonic ringtones, and up to twelve different SIP identities. This is the meaning of independence in every day work. To guarantee maximum of comfort the user interface of the snom 870 is designed especially for a clear and intuitive operation.

All phone keys are arranged that they are easy to see and reach from almost any angle, regardless of whether the snom 870 is set up with the footstand in the high or low position.
 
The new look of the snom 870 was designed in cooperation with very renowned German industrial designers - and this first model of the new product line of snom phones is living up to the highest expectations in functionality and timeless beauty.

Please note that all Snom Phones come with a Power Adaptor and are PoE compatible
