Embedded Linux brings high-quality conferencing to VoIP phone
Jun 3, 2005 — by Henry Kingman — from the LinuxDevices Archive — viewsSnom is shipping a Linux-based VoIP (voice-over-IP) business phone said to offer high-quality conferencing, thanks to on-phone bridging and a full-duplex speakerphone. Snom will demonstrate the Snom 320 at SuperComm in Chicago next week, along with its full line of Linux-based VoIP phones, equipment, and software.

According to Snom, the 320's on-phone bridging capability cuts total conference-call bandwidth by a third, while minimizing “round-trip latency.” Distributed bridging also reduces the signal-processing load on central IP-PBXs (IP private branch exchanges) and host communications servers, the company says.
Additional features of the Snom 320 include:
- 2 x 24 semi-graphic LCD display
- 12 programmable keys
- 100-number call memory and onboard address book
- Custom call blocking
- Downloadable ring-tones
- Dialing and configuration through keypad or Web interface
- Centrally manageable
- Firmware upgradable
- Broad codec support
- Compatible with current SIP recommendations
- STUN (simple traversal of UDP through NAT)
- ENUM (for dialed-number resolution)
- SRTP (secure real-time transport protocol) support prevents eavesdropping and sniffing
Snom's line of Linux-based SIP phones includes the large-display 360, the basic but high-security 190, the extensible 220, and the original 100. Snom also sells Linux-based SIP IP-PBXs, such as the 50-user VoIP Box (pictured at right) launched in February. Its other products include Linux-based enterprise and carrier class communications servers, media servers, PoE servers, and VoIP software suites.
Snom CEO Christian Stredicke, Ph.D., said “The Snom 320 is engineered for flexible deployment with SIP-standard IP PBX appliances, enterprise-grade VoIP premise equipment, or hosted services.”
Availability
The Snom 320 is available now in Snom's online store, priced at $250, or through Snom's global VAR network, with a suggested retail price of $199.
