SNOM-821B
Gigabit IP Phone 12 Lines, 320x240 Colour Screen, PoE, Black
The snom 821 replaces the snom 820 as the entry model of a new generation of snom VoIP business phones.
With this new 8xx series, currently consisting of the snom 821 and the snom 870, two main requirements of modern telephony are realised without compromise in one device: mature VoIP technology and a design in a class of its own.
The SIP-based phone is optimised for professional use, from a technical standpoint as well as from its look. The SNOM-821 comes with an integrated 1 Gigabit switch on board which enables connected devices to benefit from all modern network installations.
With its high-resolution TFT color display it offers a brilliant depiction of call lists, phone directories, and caller information via the integrated XML browser.
The wideband technology (snom klar-VOICE) used in the handset makes the user feel as if the caller were in the same room. In hands-free-mode, a Class D amplifier reliably suppresses interference noise.
Furthermore it includes the use of secure VPN as well as TLS and SRTP, making it almost impossible to hack or misuse data. The SNOM-821 comes ready to be used with the snom WLAN adapter through the USB Type A connector on the phone.
All keys are extremely easy to see and reach from almost any angle, whether it is set up with the footstand in high (55°) or low (33°) position!
