The Snom 320: A powerful yet affordable IP Phone.

This business class Snom phone is loaded with excellent features such as a 2x24 semi-graphical LCD display, which allows for easy viewing of callers, your call log and address book, 12 programmable keys and a 100 number call memory.

The Snom 320 also features custom call blocking, configurable/ downloadable ringtones, auto answer mode, do not disturb and many other practical features.

Management is easy with the Snom 320 because it is remote-manageable and firmware-upgradeable making it uniquely easy to install, and largely self-configuring.

The Snom 320 has 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.
