Snom 820 IP Phone

The snom 820 IP Phone is the beginning of a superior line of business VoIP phones. It''s extraordinary elegance and performance combines both: latest technology and well known snom features. The snom 820 IP Phone is an amazing experience for everybody who is used to the basic world of telephony.

The snom 820 IP Phone is the beginning of a new business phone series from snom.  It is like the prelude of a new masterpiece in VoIP technology. In this series we want to merge two of the main requirements of modern telephony in one device:  mature VoIP technology and design in a class of its own.

Display

With its large high-resolution TFT color display (8,9 cm (3.5”), 320 x 240 pixels) the snom 820 IP Phone offers a brilliant depiction of call lists, phone directories, and caller information via the integrated XML browser.

Audio

The wideband technology used in the handset captures more than double of the spectrum of voice frequencies that by standard phones. This means the audio quality can be compared to FM radio. On speakerphone a Class D amplifier reliably suppresses interference noise. This means high power conversion efficiency combined with an excellent sound.

WLAN and Security

Additionally, the new snom 820 IP Phone WLAN enables you to install the phone in any surrounding you are. Whatever you prefer, the snom 820 IP Phone is prepared for any option: Power over plug with WLAN or Power over Ethernet (PoE). Moreover, the snom 820 IP Phone 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 820s 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 achieve.

Conferencing and Functions

But the snom 820 IP Phone also offers a wide range of functions particularly relevant to the business world, like 5-way conferencing, multiple ringtones, and up to twelve different SIP identities. This is the meaning of independence in every day work. To guarantee maximum comfort the user interface of the snom 820 IP Phone 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 820 IP Phone is set up with the footstand in the high or low position.

Design

The new look of the snom 820 IP Phone 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 IP Phones come with a Power Adaptor and are PoE compatible.
