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.
A 2 x 24 semi-graphical LCD display and menu-driven user
interface support 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
ring-tones, auto-answer mode, DND and other sophisticated features
ensure convenience and productivity.
And the snom 320’s built-in web server supports even simpler enduser
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 audio quality and low latency.
