VG 202 Analog Phone
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.

 

 

 

 

The Cisco 112-FXS Bundle (Figure 1), Cisco VG 224 (Figure 2), Cisco VG 204 (Figure 3), and Cisco VG 202 (Figure
4) are Cisco IOS® Software-based analog phone gateways. The Cisco 112-FXS Bundle is a high-density 112-port
gateway, Cisco VG224 is a 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 (UCM). Having these devices tightly

integrated with the IP-based phone system is advantageous for increased manageability, scalability, and costeffectiveness
(Figure 5). Commercial businesses can also use the Cisco 112-FXS Bundle, 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. 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 (Figure 5).
The Cisco 112-FXS Bundle, Cisco VG 224, Cisco VG 204 and Cisco VG 202 offer Cisco IOS Software manageability
on analog phone lines to enable them to be used as extensions to the Cisco Unified Communications Manager or
Cisco Unified Communications Manager Express system. The Cisco 112-FXS bundle and Cisco VG 224 offers 19-
inch rack-mount chassis, while the Cisco VG204 and Cisco VG202 offer desktop form factor chasses with fanless
design.

 

Features and Benefits
● Cisco IOS Software-Based Hardware: The hardware includes uniform Cisco command-line interface (CLI)
and Simple Network Management Protocol version 3 (SNMPv3) support for ease of gateway configuration
and operation.
● Robust Voice Quality: Cisco experience in providing toll-quality packet-voice service helps ensure that the
Cisco 112-FXS Bundle, Cisco VG 224, Cisco VG204 and 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 112-FXS Bundle and Cisco VG 224
is the ideal platform to support centralized analog phone line deployments, while Cisco VG 204 and Cisco VG
202 are ideal platforms 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. Cisco 112-FXS Bundle and Cisco VG 224 can also be used in a Cisco Unified
Communications Manager Express environment and migrated to Cisco Unified Communications Manager
deployment with 100 percent investment protection.
● High Availability: Customers will experience less voice downtime due to WAN link failure. Cisco 112-FXS
Bundle, Cisco VG 224, Cisco VG 204 and Cisco VG 202 have 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.
Cisco 112-FXS Bundle is built on Cisco Integrated Services Routers Generation 2 (ISR G2) platform powered
by high-performance multicore processors. In this platform, power redundancy is available by installing an
optional integrated RPS, thereby decreasing network downtime and protecting the network from power-supply
failures. Cisco VG 224 offers high-availability during power failure using an external 12V DC UPS for battery
backup.
● Reduced Barrier to Entry: These analog phone gateways provide 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.
