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.
