Built on a powerful combination of the Asterisk open source communications engine and a state-of- the-art embedded platform, Digium’s digital gateways provide the best value for connecting traditional telephony (T1/E1/PRI) to IP (SIP). Digium’s 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.
