Analog VoIP Gateways

G080 Analog Gateways

Built on a powerful combination of the Asterisk open source communications engine and a state-of- the-art embedded platform, Sangom’s G080 analog gateways provide the best value for connecting traditional telephony (loopstart FXO to FXS) to IP (SIP). Sangoma’s G080 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 G080 Series VoIP gateways are 8-port analog gateways with the ability to support up to 8 concurrent calls. Sangoma 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.

The G080 series analog VoIP gateway is available in:

  • 8 Port Analog FXO
  • 8 Port Analog FXS
  • 4 Port Analog FXS and 4 Port Analog FXO
