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 Gateways 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 additional ISDN lines for PSTN calls.
Minimal conguration is needed,
the Quadro IP PBX will automatically
use the new ISDN ports and present them
within its management system as additional ISDN lines. These lines may be colocated with the IP PBX or located remotely
as an “extension cord” to another ofce in another 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 conguration you remove the IP PBX altogether by assigning VoIP network
DID numbers from an ITSP directly to the Quadro Gateway lines. It truly is the lowest cost for creating a local
presence anywhere on the globe.
