Digium G400 VoIP Gateway


The Digium G400 is a higher density four (4) port gateway appliance designed to connect legacy voice technologies (T1/E1/PRI) to VoIP as well as transcoding SIP protocols between VoIP devices and/or service providers. 

Additional benefits of the G400 include dual Ethernet ports for separate management or voice paths, 120 call capacity, no additional licenses to purchase, no moving parts and the same form factor as the existing Digium G100 and G200 gateways. 

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.
