Innovative SIP based VoIP 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 confer-
ence bridging.
A 2 x 24 semi-graphical LCD display
and menu-driven user interface sup-
port easy feature management.
12 programmable keys with LEDs sup-
port flexible identity access/key con-
figuration. 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 pro-
ductivity. 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-con-
figuring. Broad codec support and full
compatibility with current SIP rec-
ommendations ensure interoperabil-
ity; 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 specifi-
cation from the Internet Engineer-
ing Task Force (IETF) for protection
against eavesdropping – and TLS for
protection against sniffing of signaling
and authentication data.
By limiting the need for external con-
ference bridges/media server capacity
or use of conference services for rou-
tine 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.
