Built on a powerful combination of the Asterisk open source communications engine and an excellent embedded platform, Digium's analog gateways provide great value for connecting traditional telephony (loopstart FXO to FXS) to IP (SIP). The G080 Series VoIP gateways are 8-port analog gateways with the ability to support up to 8 concurrent calls. Digium gateways' robust feature set includes the ability to configure call rules for connecting many combinations of telephony providers (traditional and VoIP) and PBXs (legacy and VoIP), failover routing to ensure calls won't fail, SIP to SIP transcoding, and a proven design with no moving parts that fits any environment.
