Cisco Voice Gateways
Voice Gateways interface directly to PBXs or public telephone networks to carry voice
traffic across IP networks—by converting IP calls to standard telephony calls and vice
versa. They provide connectivity between packet telephony and legacy telephony such as
PSTN, PBX, fax machines, and other devices. Cisco offers the Cisco VG 248 and VG 224
dedicated analog voice gateways.
Cisco’s full line of multiservice routers can also add analog and digital voice gateway
functionality through the use of network modules and voice interface cards

.
Cisco VG 224 Voice 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. Commercial
businesses can also use the Cisco VG 224 in conjunction with Cisco CallManager Express
to effectively augment a Full Service Branch router environment. This topology
environment supports a businesses needs of high concentration of analog voice ports for
basic calls, with some supplementary services.
Cisco VG248 Voice Gateway
The Cisco VG248 Voice Gateway is a 1 unit high rack mountable device allowing 48 analog
devices (phones, fax machines & modems) to be used with Cisco Call Manager. It enables
organizations with large numbers of analog phones (hotels, universities, hospitals, etc.) to
deploy IP Telephony while maintaining the investment in legacy handsets. The analog lines
are full featured (caller id, message waiting lights, feature codes) and the price per port is
competitive with a legacy PBX.
The VG 248 supports the legacy voicemail Simple Message Desk Interface (SMDI) mail
interface that allows the connection of a Cisco Call Manager network to a legacy voicemail
system. It also will allow the sharing of existing SMDI based voicemail systems between
the Cisco Call Manager and the legacy PBX.
