Data Sheet

Cisco VG350, VG224, VG204XM, and VG202XM

business processes, reach the right resource the first time, and improve productivity and profitability (Figures 1

through 4). 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.

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 3

Figure 6. Cisco Voice Gateway Integration with Cisco Unified Communications Manager Express

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.

The Cisco VG350, VG224, VG204XM, and VG202XM support feature access codes (FACs) in conjunction with

Cisco Unified Communications Manager and Cisco Unified Communications Manager Express. Refer to

documentation for these applications for details.

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.
