Snom 320 - VoIP-Info

Snom 320 2-Line SIP based IP phone

Ideal for the office and everyone who makes a lot of calls, the snom 320 is an affordable, yet powerful SIP business telephone with built-in full duplex speakerphone and three-party conference bridging.

How does it work?
Hailing from Germany, Snom is fast gaining ground in the SIP marketplace. Snom phones offer excellent interoperability with Asterisk Open Source PBX, Trixbox, PBXnSIP and other SIP based platforms.

The Snom 320 is Snom’s mid-level, SIP based IP phone. For under $200, you get an LCD display and programmable function keys, dual onboard ethernet ports, PoE multiple line appearances, full duplex speakerphone and a range of codec support.

A 2 x 24 semi-graphical LCD display and a menu-driven user interface supports easy feature management.

12 programmable keys with LEDs support flexible identity access/key configuration. A 100 number call
memory, a 100 entry onboard address book (to which data may easily be uploaded),custom call blocking, configurable/ downloadable ringtones,auto-answer mode, DND and other sophisticated features ensure convenience and productivity. And the snom 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- upgradable, uniquely easy to install, and largely self-configuring.
Broad codec support and full compatibility with current SIP recommendations ensure interoperability;support for STUN (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 the 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 ensuring high
