Digital VoIP Gateways

G200 Digital Gateways

Built on a powerful combination of the Asterisk open source communications engine and a state-of- the-art embedded platform, the G200 digital gateways provide the best value for connecting traditional telephony (T1/E1/PRI) to IP (SIP). The G200 gateway software is based on the Asterisk communications engine and is managed through an intuitive point-and-click GUI, which allows for easy navigation and effortless setup. The digital gateways feature a power-saving embedded design with a highly efficient digital signal processor (DSP) handling all media-related operations.

The G200 VoIP Gateway includes two (2) software-selectable T1/E1/PRI interfaces and supports up to 60 concurrent calls. With a robust feature set including the ability to configure calling rules for connecting many combinations of telephony providers (traditional and VoIP) and PBX’s (legacy and VoIP), failover routing to ensure calls won’t fail, licensing for the maximum number calls the appliance supports, SIP to SIP transcoding and a proven design of no moving parts to fit any environment, G200 Gateways are proven to support most applications.

The G200 digital VoIP gateway is available in:

  • Two Span Digital T1/E1/PRI to VoIP Gateway Appliance
