CISCO VG 224 ANALOG PHONE GATEWAY
®
The Cisco VG 224 Analog Phone Gateway enables an IP Telephony solution to continue using traditional analog devices while taking advantage of the productivity afforded by IP infrastructure. Figure 1. Cisco VG 224 Analog Phone Gateway
The Cisco VG 224 is a Cisco IOS® high-density 24-port gateway for analog phones, fax machines, modems, and speakerphones within an enterprise voice system based on Cisco CallManager. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness (see Figure 2). Commercial businesses can also use the Cisco VG 224 in conjunction with Cisco CallManager Express to effectively augment an Integrated Services Router (ISR) environment. Either topology environment will support business need for a high concentration of analog voice ports for modem calls, fax calls, and analog supplementary services (see Figure 3). The Cisco VG 224 offers Cisco IOS manageability with 24 analog phone lines to be used as extensions to the Cisco CallManager or Cisco Call Manager Express system in a very compact 19-inch rack-mount chassis. FEATURES AND BENEFITS • Cisco IOS Based Hardware—Uniform Cisco command-line interface (CLI) and Simple Network Management Protocol version 2 (SNMPv2) 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 provides 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 analog phone lines, 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 CallManager Express environment and migrated to Cisco CallManager deployment with 100 percent investment protection. • High Availability—Customers will experience less voice downtime due to WAN link failure. Cisco VG 224 has 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 CallManager. Cisco VG 224 also can use a 12V DC UPS for up to 8 hours of battery backup. • Reduced Barrier to Entry—Provides 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 is ideal for implementations in which analog phones are needed. The VG 224 provides a high level of availability at locations with MGCP Fallback, with ease of manageability using Cisco IOS monitoring features. Cisco VG 224 offers many supplementary analog calling features depending on the call control and signaling type used. Please refer to Table 1 for the supplementary analog calling features available.

FAX AND MODEM CONNECTIVITY The Cisco VG 224 supports fax machines and modems. When using fax machines, the Cisco VG 224 supports 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 and will be transferred over the network using modem passthrough. PROTOCOLS SUPPORTED • SCCP • H.323v4
