Digium Gateways

Digium's VoIP gateways are cost-effective, industrial grade appliances that simplify the process of deploying converged media networks. Digium's G100, G200, G400, and G800 VoIP Gateways are, respectively, 1, 2, 4, and 8-port software-selectable T1/E1/PRI appliances that support up to 30, 60, 120, and 240 concurrent TDM to SIP calls. Digium G080 Series VoIP Gateways are 8-port analog appliances that are provided in one of three configurations: 8 FXO, 4 FXS + 4 FXO, or 8 FXS interfaces. They are built to support TDM-to-SIP, SIP-to-TDM and SIP-to-SIP (transcoding) applications. In a TDM-to-SIP deployment the VoIP gateway significantly reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services. SIP-to-TDM deployments use the VoIP gateway to connect a modern SIP communications system with T1/E1/PRI service from legacy carriers.  SIP-to-SIP deployments are also possible, with call concurrency halved as compared to operations involving both SIP and TDM interconnection.
