SIP based VoIP Phone
The IP telephone with the latest VoIP
technology for the discerning caller! Ide-
al for ITSPs, offices, and private users.
As the basic model of the snom business
telephone family, the SIP telephone
snom 300 fulfils the requirements of
VoIP telephony and additionally offers
numerous functions that are indispens-
able for everyday working life. Due to
its excellent cost-performance ratio, it
is ideal both for ITSP packages/prod-
ucts and for small and medium-sized
enterprises, home offices, and private
users.
The snom 300 sets new standards when
it comes to user-friendliness: A two-line
LCD display shows call information, and
the menu-driven user interface provides
simple feature management.
The snom 300 is synonymous with ef-
fectiveness, time saving and flexibility:
It provides all necessary office function-
alities, for example choice of outgoing
identity, “busy” indication, or picking
up calls. Four identities are possible.
Six user- or administrator-configurable
(or carrier-preconfigurable) function
keys can easily be allocated to arbitrary
menu functions like DND, redirection,
deny, etc., or assigned to multiple lines.
The snom 300 comes factory-equipped
with two of its six programmable keys
configured as line appearances. You
can configure up to all six function keys
this way – flexible enough to suit the
needs of every user.
Are you afraid of unsolicited eavesdrop-
pers, data theft, or spam calls? Thanks
to the snom 300 you have no need to
worry. Due to the security standards
SRTP and SIPS, the snom 300 is just
as secure as the business models snom
360 and 320. This makes it perfectly
suited for use in sensitive environments
such as in banks and medical or mili-
tary establishments.
