VG 202 Analog Voice Gateways enable
an IP telephony solution to continue using traditional analog devices while taking
advantage of the productivity afforded by IP infrastructure.
The Cisco Unified Communications system of voice and IP communications products and
applications enables organizations to communicate more effectively—helping them to streamline
business processes, reach the right resource the first time, and impact the top and bottom line.
The Cisco Unified Communications portfolio is a key part of the Cisco Business Communications
Solution—an integrated solution for organizations of all sizes which also includes network
infrastructure, security, and network management products, wireless connectivity, and a lifecycle
services approach, along with flexible deployment and outsourced management options, end-user
and partner financing packages, and third-party communications applications.

Software-based analog voice gateways. The Cisco VG224 is a high-density 24-port gateway,
and the Cisco VG 204 and Cisco VG 202 are low-density 4 and 2 port gateways, respectively.
These gateways connect analog phones, fax machines, modems, and speakerphones to an
enterprise voice system based on Cisco Unified Communications Manager (Figure 4). Having
these devices 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 224, Cisco VG 204 and Cisco VG 202 with Cisco Unified Communications Manager Express to
effectively augment an integrated services router (ISR) environment (Figure 5). 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.
