The Voice over IP Gateway
The Quadro Gateway to PSTN, ISDN BRI Extension and/or Mini POP
Gateway to the PSTN
The Quadro Gateway is a modular approach to adding
additional outside PSTN lines (ISDN BRI) to a corporate
phone network that uses Epygi’s Quadro IP PBXs. Each
Quadro Gateway is a stand-alone SIP gateway device
with 4 outside ISDN BRI lines. Multiple Quadro Gate-
ways can be added to a Quadro IP PBX depending on
how many additional lines are required. Uses include
the addition of inbound lines, the balancing of out-
bound call volumes from a combination of analog and
IP phones, fax lines, emergency lines and individual di-
rect dial numbers for each member of staff.
ISDN BRI Extension for Quadro IP PBX
Connected via Ethernet to the LAN
interface of a Quadro IP PBX, the
Quadro Gateway delivers four ad-
ditional ISDN lines for PSTN calls.
Minimal configuration is needed,
the Quadro IP PBX will automatically
use the new ISDN ports and present them
within its management system as addi-
tional ISDN lines. These lines may be co-
located with the IP PBX or located remotely
as an “extension cord” to another office in an
-
other city or even another country.
Mini Point of Presence (POP)
The Quadro Gateway can be used as a low cost, mini
Point of Presence (POP). In this configuration you re
-
move the IP PBX altogether by assigning VoIP network
DID numbers from an ITSP directly to the Quadro Gate-
way lines. It truly is the lowest cost for creating a local
presence anywhere on the globe.
