Cisco VG200 Series Gateways

Cisco VG 224, VG 204 and VG 202 Analog Phone Gateways

Downloads

The Cisco® VG 224, Cisco® VG 204 and Cisco® 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.

The Cisco VG 224 (Figure 1), Cisco VG 204 (Figure 2), and Cisco VG 202 (Figure 3) are Cisco IOS® 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.
The 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 VG 224 offers a very compact 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 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 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 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 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 VG 224 offers additional high-availability during power failure using an external 12V DC UPS for battery backup.

• Reduced Barrier to Entry: These analog voice 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.

Analog Phone Connectivity

The Cisco VG 224, Cisco VG 204 and Cisco VG 202 are ideal for analog phone deployments ranging from centralized to sparsely concentrated or distributed topologies. These analog voice gateways provide a high level of availability at locations with MGCP Fallback, with ease of manageability using Cisco IOS Software monitoring features. They offer many supplementary analog calling features depending on the call control and signaling type used. Refer to Table 1 for the supplementary analog calling features available.

Refer to Cisco Unified Communications Manager and Cisco Unified Communications Manager Express documentation for details.

Fax and Modem Connectivity

The Cisco VG 224, Cisco VG 204 and Cisco VG 202 support fax machines and modems. When using fax machines, they support Cisco fax relay, T.38 fax relay, and fax passthrough. Cisco or T.38 fax relay technologies allow transfer of faxes across the network with high reliability using less bandwidth than a voice call. All modems can be connected to the Cisco VG 224, Cisco VG 204 and Cisco VG 202 and will be transferred over the network using modem passthrough.
