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.
