A 2 x 24 semi-graphic LCD display and menu-driven user interface supports custombranding and easy feature management. 12 programmable keys with LEDs supportflexible trunk-access/busy lamp configuration.

A 100-number call memory, 100-number onboard address book (to which data mayeasily be uploaded), custom call blocking, configurable/downloadable ring-tones, auto-answer mode, DND and other sophisticated features insure convenience andproductivity. And the 320's built-in web server supports even simpler end-userconfiguration, screen dialing, and access to call history.

The snom 320 is remote-manageable and firmware-upgradeable, uniquely easy to install, and largely self-configuring. Broad codec supportand full compatibility with current SIP recommendations insures interoperability;support for STUN (for NAT traversal), ENUM (for dialed-number resolution) andother state-of-the-art features enables flexible deployment, behind local proxies, IP PBXs or hosted VoIP services.

The snom 320 supports the security standard SRTP - a currentspecification from the Internet Engineering Task Force (IETF) for protectionagainst eavesdropping - andTLS for protection against sniffing of signalingand authentication data.

By limiting need for external conference bridges/media server capacity or useof conference services for routine multiparty calls, the snom 320'sbuilt-in three-party conference bridge helps limit total cost of ownership, while also insuring high audio quality and low latency.
