Essentially, the Quadro FXO gateway is a modular approach to adding additional outside PSTN or traditional telephone service lines to a corporate phone network that utilizes an Epygi Quadro IP PBX. Each QuadroFXO is a stand-alone SIP gateway device consisting of a VPN-router, firewall, HTTP server, and call processing software.

The FXO includes advanced PBX features and integration with any Quadro IP PBX is pure plug-and-play. If ports are in short supply, you can add multiple gateways to the IP PBX. Devices recognize each other and auto-configure.
The Quadro FXO Gateway can be used stand-alone as well, without an IP PBX (as with IP Centrex for example). The six FXO lines can be assigned VoIP network DID numbers by an ITSP.

The Quadro ISDN Gateway performs similarly to the FXO version but connects using ISDN ports. The gateway includes four ISDN BRI connections for phones and analog devices that can connect to the telephone company's central office or to a local PBX.

The Quadro ISDN can be used to add inbound lines, balance outbound call volumes from a combination of analog devices and IP phones.

Each Quadro ISDN is a stand-alone SIP gateway device that includes a VPN-router, firewall, HTTP server, and call processing software. Installing the Quadro ISDN requires very little configuration. A Quadro IP PBX will automatically present the new ISDN ports within its management system. The lines can be local within the office or used as an "extension cord" to remote branches.

Note: ISDN is not widely supported in the USA. It is intended for all other countries with large networks of ISDN-based service providers. If you are unsure of ISDN support in your region please contact your dealer or Epygi Technologies directly for clarification.

The Quadro E1/T1 connects to an traditional enterprise PBX or directly to a high capacity, usually fiber optic T1 (North America and Japan) or E1 (the rest of the world) from the PSTN telephone network. Its primary function is to bridge a portion of traffic of an incumbent proprietary PBX to the Internet.

A Quadro E1/T1 comes equipped with one FXS port for connection of a standard analog telephone or fax machine. In addition, there is one software configurable E1/T1 voice port. Your voice and data traffic are routed through the WAN port to the Internet.

Your company can make as many as 30 simultaneous SIP VoIP calls through a single Quadro E1/T1. The Quadro E1/T1 integrates PBX, security and traffic management functions and supports most signaling protocols including R2, CAS, and CCS (PRI).
