Technical Data: Quadro4xi
The Global Phone Network in a Box
The Quadro4xi is the fully-featured ISDN IP PBX for
small businesses. Connected by one ISDN line to the
PSTN and over 10Base-T Ethernet to the Internet, the
Quadro4xi allows to make up to 20 calls in parallel.
Besides four FXS phones, up to 62 fully-featured SIP
phones may be attached to Quadro4xi’s LAN port. In
addition, all extensions assigned to a line may be mir-
rored and act as remote IP extensions. Wherever you
are, calls will reach you, and you will be able to make
calls as if you were in your office.
Fully-Featured IP PBX
The Quadro4xi offers the same multitude of features
as Quadro4x: extensive PBX functionality, integrated
voicemail, cost saving call routing functionality, IP
routing, SIP call signaling and much more.
Integrated Internet Access Router
The Quadro4xi IP PBX embodies a fully-
fledged Internet access router with fire
-
wall security, including IDS, NAT, policy
and service based filtering as well as
stateful inspection. An extensive IPSec
VPN functionality with DES, 3DES and AES
encryption makes an additional contribution to data
security.
VoIP Carriers
The Quadro4xi IP PBX is easily applicable for VoIP Car-
riers as well as small businesses. For VoIP carriers, a
special wizard has been implemented that facilitates
the configuration of the Quadros to work according
to individual requirements.
