Built on a powerful combination of the Asterisk Open Source communications engine and a state-of- the-art embedded platform, Digium VoIP Gateways provide the best value for connecting disparate topologies of traditional telephony (T1/E1/PRI) to IP (SIP).


The gateway software is based on the Asterisk communications engine and is managed through Digium’s intuitive point-and-click GUI, which allows for easy navigation and effortless setup. VoIP gateways feature a power-saving embedded design with a highly efficient digital signal processor (DSP) handling all media-related operations.

The Digium G400 VoIP Gateway includes four (4) software-selectable T1/E1/PRI interfaces and supports up to 120 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, Digium Gateways are proven to support most applications.
