The Cisco VG 202 Analog Voice Gateway enables an IP telephony solution to continue using traditional analog devices while taking advantage of the productivity afforded by IP infrastructure.

The Cisco VG 202 is Cisco IOS software-based analog voice gateway. It is a low-density 2-port gateway. This gateway connects analog phones, fax machines, modems, and speakerphones to an enterprise voice system based on Cisco Unified Communications Manager. Having this device tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. Commercial businesses can also use the Cisco VG 202 with Cisco Unified Communications Manager Express to effectively augment an integrated services router (ISR) environment. Either topology environment will support business needs, ranging from high to low concentration of analog voice ports for modem calls, fax calls, and analog supplementary services.

Product Features

  • Robust voice quality
    Cisco experience in providing toll quality packet voice service helps ensure that the Cisco VG 202 provide the clear, robust voice quality end users have come to expect from telephony services.
  • Investment protection
    Customers can continue to use existing analog phones, fax machines, and modems while taking advantage of IP telephony. Basic analog phone connectivity is needed when the infrastructure (wiring) or application does not support or require IP phones. The Cisco VG 202 is an ideal platform to support sparsely concentrated, distributed analog phone deployments, allowing organizations to deploy IP telephony without having to purchase IP phones for all users and to continue using existing devices.
  • High availability
    Customers will experience less voice downtime due to WAN link failure. Cisco VG 202 has built-in Media Gateway Control Protocol (MGCP) failover to an H.323 connection to a Survivable Remote Site Telephony (SRST) router. This failover will maintain voice service for analog endpoints in the event of WAN link failure and lost connectivity to the Cisco Unified Communications Manager.
  • Reduced barrier to entry
    This analog voice gateway provides a low-cost alternative for low-end analog phones and allows organizations to take advantage of IP telephony with a lower overall IP telephony investment.
