The Cisco VG Series Analog Voice Gateways are Cisco IOS software-based. The Cisco VG310 is a 24-port gateway. The gateway connects analog phones, fax machines, modems, and speakerphones to an enterprise IP voice system, so you can use them as extensions to your Cisco or third-party IP call-control system. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. The Cisco VG Series supports high to low concentrations of analog voice ports for modem calls, fax calls, and analog supplementary services.
The VG310 is built on the Cisco 2901 platform, powered by a single high-performance core processor. It provides high availability during power failure through an external universal power supply (UPS).
