About Snom

Ideal for the office and everyone who spends a lot of time on the phone, the Snom 320 is an affordable, yet powerful SIP business phone with built-in, full-duplex speakerphone and three-party conference bridging. A 2 x 24 semi-graphic LCD display and menu-driven user interface support an uncomplicated feature management. 12 programmable keys with LEDs support quick access to important extensions.

Call list and address book can contain up to 100 entries each and entries can be added and changed easily. Other features like blocking anonymous calls, downloading ringtones, auto-answer mode, DND mode and other features are only examples from an abundance of functions which make phone use convenient and comfortable while increasing productivity.

Additional applications like CTI further enhance the functionality. Installing the Snom 320 is child's play and possible on the phone itself as well as by remote configuration. Further advantages are extensive Codec support and wide-ranging compatibility with SIP components made by other manufacturers. The support of STUN, NAT, ENUM and numerous other functions allows flexible utilization behind local proxies, IP PBXs and hosted VoIP services.

Concerning security, the Snom 320 protects you with SRTP and TLS against wiretapping and unwanted access to signaling and authentication data. The Snom 320's built-in three-way conference bridge eliminates external devices and services while offering high audio quality and minimal latency. These savings together with the Snom 320's very low energy consumption (1.0 to 1.5 w-hrs in standby) and PoE (Power over Ethernet) truly help to lower your costs.
