The snom 821 White represents a superior line of business VoIP phones and  comes with an integrated 1 Gigabit switch on board, enabling connected devices to benefit from all modern network installations. 

Display and Wideband Technology

With its large high-resolution TFT color display (8.9 cm (3.5 inch), 320 x 240 pixels) the Snom 821 IP Phone offers a brilliant depiction of call lists, phone directories, and caller information via the integrated XML browser. The wideband technology used in the handset captures more than double the frequency spectrum that a standard handset does, making the audio quality comparable to FM radio. On speakerphone a Class D amplifier reliably suppresses interference noise.

WLAN and Security

The Snom 821 White IP Phone's WLAN gives you complete freedom in selecting the environment of your choice. Whichever option you prefer, the Snom 821 IP Phone is prepared for any and all scenarios; Power via adapter plus WLAN or Power-over-Ethernet (PoE). Moreover, the Snom 821 IP Phone offers all conveniences Snom customers have come to expect. As security is one of the most important concerns of our time, this topic has always been a priority for Snom. Therefore important security features like secure VPN, TLS and SRTP are an integral part of the 821's firmware. The continuing goal is to ensure that the customers' data is protected effectively from any unauthorised accessing.

Note: The Snom 821 White IP Phone is interoperable with Windows OCS. Please see the following links:
