If you’re looking for a way to improve your modular approach to adding additional outside PSTN lines (POTS) to a corporate phone network that uses an Epygi (News - Alert) Quadro IP PBX, or if you’re interested in the advantages of such a setup, you might want to look into the QuadroFXO for unified messaging.

Each QuadroFXO, according to company officials, is a stand-alone SIP gateway device with six outside POTS lines. As company officials say, multiple QuadroFXO gateways can be added to a Quadro IP PBX (News - Alert), “depending on how many additional lines are required.”

It’s connected via Ethernet to the LAN interface of a Quadro IP PBX, and minimal configuration is needed, since the Quadro IP PBX will automatically use the new POTS ports and present them within its management system as additional FXO lines, according to company officials.

And these lines may be co-located with the IP PBX or located remotely -- “as an ‘extension cord’ to another office in another city or even another country,” company officials say.

And if you want, you can use the QuadroFXO as a low cost, mini Point of Presence (POP), which would let you remove the IP PBX altogether by assigning VoIP network DID numbers from an ITSP directly to the QuadroFXO lines.

Setting the Way-Back Machine a few years, in 2005 TMC had the news that Epygi Technologies (News - Alert), “a manufacturer of IP PBXs, VoIP gateways, and conference servers,” announced that it will showcase its newly designed QuadroFXO and version 3.1 IP PBX software at Internet Telephony (News - Alert) Conference and Expo Fall 2005 later this month at the Los Angeles Convention Center.

Highlighting just one of its many features, company officials at the time said “the Quadro 3.1 IP PBX software will offer users enhanced functionality by providing features designed specifically for receptionists, call pickup, simplified IP phone installation, and auto configuration when connecting the QuadroFXO to Epygi IP PBX systems.”

The QuadroFXO was described at the time as “a low cost 6-port FXO gateway that allows IP PBX users to expand the number of POTS lines that can be connected to an IP PBX system. Providing additional POTS lines for emergency calls, lifeline, and mission critical fax calls are a high priority for many small businesses.”
