Overview:

You don’t have to replace your entire phone system as you move to unified communications. Cisco VG Series Gateways help you migrate at your own pace and budget by taking full advantage of the investments you have already made. Cisco VG Gateways allow you to enjoy the benefits of unified communications while using your existing analog phones and fax machines.

The Cisco VG224 Analog Voice Gateways allow you to use your IP telephony solution with traditional analog devices while taking advantage of the productivity afforded by IP infrastructure.

Cisco VG224 Analog Gateway:

  • Standalone solution for medium-density for deployments of 24 lines or less
  • Combines a high-density RJ21 analog interface with Cisco IOS Software manageability to increase the functionality of analog equipment
  • Offers gateway capabilities for analog voicemail systems
  • Housed in a compact, 19-inch rack-mount chassis

Cisco Unified Communications enables organizations to collaborate more effectively - helping them streamline business processes, reach the right resource the first time, and improve productivity and profitability. Cisco offers an end-to-end unified communications and collaboration solution that includes network infrastructure, security, unified call control, endpoints, network management, and a lifecycle services approach. In addition, it offers flexible deployment models, outsourced management options, end-user and partner financing packages, and integration with third-party communications applications.

Cisco VG Series Gateways

The Cisco VG350, VG224, VG204XM, and VG202XM are part Cisco IOS software-based VG series stand-alone analog voice gateways. The Cisco VG350 is a high-density 160-port gateway, the Cisco VG224 is a 24-port gateway, and the Cisco VG204XM and VG202XM 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 (Unified CM). Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness (refer to Figure 5 later in this document). Commercial businesses can also use these gateways with Cisco Unified Communications Manager Express to effectively augment an integrated-services-router (ISR) environment. Both topology environments support business needs ranging from high to low concentrations of analog voice ports for modem calls, fax calls, and analog supplementary services.

The Cisco VG350, VG224, VG204XM, and VG202XM offer Cisco IOS Software manageability on analog phone lines so that you can use them as extensions to your Cisco or 3rd party IP call control solution. The Cisco VG350 and VG224 offer 19-inch rack-mount chassis, and the Cisco VG204XM and VG202XM offer desktop form-factor chasses with a 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 VG350, VG224, VG204XM, and VG202XM provide the clear, robust voice quality end users have come to expect from telephony services.
  • Investment protection: You can continue to use your 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 VG350 and VG224 offer ideal platforms to support centralized analog phone-line deployments, and the Cisco VG204XM and VG202XM are ideal platforms to support sparsely concentrated, distributed analog phone deployments. Thus you can deploy IP telephony without having to purchase IP phones for all users and you can continue using existing devices. You can also use the Cisco VG350 and VG224 in a Cisco Unified Communications Manager Express environment and migrate to a Cisco Unified Communications Manager deployment with 100-percent investment protection.
  • High availability: With these gateways you will experience less voice downtime due to WAN link failure. The Cisco VG350, VG224, VG204XM, and VG202XM have built-in Media Gateway Control Protocol (MGCP) failover to an H.323 connection to a Survivable Remote Site Telephony (SRST) router. This failover maintains voice service for analog endpoints if the WAN link fails or you lose connectivity to the Cisco Unified Communications Manager, Cisco Business Edition or Cisco Hosted Collabortion Solution. The Cisco VG350 is built on the Cisco Integrated Services Routers Generation 2 (ISR G2) platform powered by high-performance multicore processors. In this platform, you can achieve power redundancy by installing an optional integrated redundant power supply (RPS), which helps decrease network downtime and protects the network from power-supply failures. The Cisco VG224 offers high availability during power failure using an external 12-VDC UPS for battery backup.
  • Reduced barrier to entry: These analog phone gateways provide a low-cost alternative for low-end analog phones and allow you to take advantage of IP telephony with a lower overall IP telephony investment.

Fax and Modem Connectivity

  • The Cisco VG350, VG224, VG204XM, and VG202XM support fax machines and modems. When using fax machines, they support Cisco Fax Relay, T.38 fax relay, and fax pass-through. Cisco and 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 VG350, VG224, VG204XM, and VG202XM and are transferred over the network using modem pass-through.

Analog Phone Connectivity:

The Cisco VG350, VG224, VG204XM, and VG202XM 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.
