The PLANET VIP-281GS
VoIP GSM Gateway is a
signal-GSM channel
gateway that supports
SIP and H.323 VoIP
protocol at the same
time. The VIP-281GS
provides a total

voice-data network and
the Global System for
Mobile Communications (GSM).
The VIP-281GS is
equipped with both FXS
and PSTN interfaces,
which gives the gateway
a wide range of
potential applications.
The VIP-281GS can be
installed on a PBX trunk
line to enrich its

eliminates the human
resource of VoIP network
deployment. With
optimized H.323 / SIP
architecture, the
VIP-281SG is the ideal
choices for P2P voice
chat and ITSP
cost-saving solution,
but also provides
network-converting
feature to translate the
packet network into
traditional PBX system.
With built-in PPPoE /
DHCP / DDNS clients, up
to 2 concurrent
connections in
VIP-281GS, voice
communications can be
established from
anywhere around the
world. The VIP-281GS
comes with intuitive
user-friendly and
powerful management
interface (web /
telnet), that can
dramatically reduce IT
personnel resource and
complete GSM / VoIP
deployment in a short
time. Plus remote
management capability,
administrators can
monitor machine /
network status or
proceed maintenance /
trouble-shooting service
via Internet browser or
telnet session. Besides,
it provides voice
channels status display
and optimized packet
voice streaming over
managed and public
(Internet) IP networks.

IP addresses. It
allows you
to provide
Internet users
with a domain
name (instead of
an IP Address)to
access
Virtual
Servers.
• NAT
