Data Sheet
Cisco VG350, VG224, VG204XM, and VG202XM
Stand-Alone Analog Voice Gateways
The Cisco® VG350, VG224, VG204XM, and VG202XM 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 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 (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.

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
rd
lines so that you can use them as extensions to your Cisco or 3 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.

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.

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.
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.
