[Updated Apr. 24] — Snom is accepting advance orders for a basic model in its line of Linux-based business VoIP (voice-over-IP) phones. The Snom 300 supports six lines, and has six programmable buttons, along with a browser interface. It targets small offices, call centers, lobbies, recreation rooms, and home use.

Snom claims the 300 sets a new standard for VoIP phone ease-of-use, thanks to a simple, menu-driven user interface, four-way navigation button (pictured at right), along with a simple, two-line LCD display.

One significant interface usability feature of the device, Snom says, is an array of six buttons that can be programmed by users, administrators, or carriers. The buttons can toggle the phone between multiple lines. Or, they can be programmed to provide fast access to security or other functions. Call centers and sales agents increasingly value programmable hardware buttons that enable phones to be adapted to specific applications, according to the company.

Another touted feature is a built-in secure web server that exposes more sophisticated features through a browser interface. A PC can be be attached directly to the phone, through its built-in two-port switch.

The Snom 300 is based on an Infineon Inca processor, and runs a 2.4.20-series kernel, modified by the company, it says. The phone supports “all common compression codecs,” Snom adds, including G.729a and G.723. The device supports low-bandwidth environments, and is compatible with SIP-based equipment and systems from other manufacturers, according to the company.

Additional listed features include:

  • SRTP and SIPS provide the same security features found in Snom's other business VoIP phones
  • DHCP
  • NTP (network time protocol) clock with daylight savings time support
  • Web-based installation, configuration, and software updates
  • 100-entry addressbook and “last calls” lists
  • Number guessing, speed dialing
  • Missed calls, dialed calls lists
  • Multi-language support via NLS
  • Full-duplex speakerphone
  • Typical call features, such as ID, timer, blocking, hold, transfer, music-on-hold, and so on


Snom is currently taking order for the 300. It's line of Linux-based business VoIP phones also includes mid-range 320 and high-end 360 models.

Snom shipped its first Linux-based VoIP phone, the Snom 100, in May of 2002. It also sells soft switches, SOHO IP PBXs, and VoIP phone accessories based on open standards, such as Linux and SIP (session initiation protocol).
