snom 320 Ideal for general office and knowledge-worker environments, the snom 320 is an affordable, yet powerful SIP business telephone with built-in, full-duplex speakerphone and three-party conference bridging. A 2 x 24 semi-graphic LCD display and menu-driven user interface supports custom branding and easy feature management. 12 programmable keys with LEDs support flexible trunk-access/busy lamp configuration.
A 100-number call memory, 100-number onboard address book (to which data may easily be uploaded), custom call blocking, configurable/downloadable ring-tones, auto-answer mode, DND and other sophisticated features insure convenience and productivity. And the 320's built-in web server supports even simpler end-user configuration, 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 support and full compatibility with current SIP recommendations insures interoperability; support for STUN (for NAT traversal), ENUM (for dialed-number resolution) and other 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 current specification from the Internet Engineering Task Force (IETF) for protection against eavesdropping - and TLS for protection against sniffing of signaling and authentication data.
By limiting need for external conference bridges/media server capacity or use of conference services for routine multiparty calls, the snom 320's built-in three-party conference bridge helps limit total cost of ownership, while also insuring high audio quality and low latency.
