Product Overview

Awarded by the Internet Telephony Services Providers' Association (ITSPA) of the United Kingdom, the snom 870 VoIP telephone is our latest innovation for all modern people with high demands for future-oriented technology combined with user friendliness. The large high-definition TFT color display is not only larger than the one of its little brother snom 821, 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 up to 5 participants via simple "drag and drop".

Address Book

The well-arranged address book makes sure that each caller can be quickly identified. It offers space for additional information such as company affiliation, email 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.

Audio Quality

The audio quality of the snom 870 matches the high standards that snom customers have come to expect: wideband audio with silence supression 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 accesing the most important stock exchange sata; the snom 870 offers a lot of room for extras.

WLAN and Security

No matter where the snom 870 is used, it is prepared for anything: conventional power supply via wall socket, Power over Ethernet 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.
