Understanding How the VG248 Integrates with the
Cisco IP Telephony Network

The Cisco VG248 is a high-density gateway for using analog phones, fax
machines, modems, and speakerphones within the Cisco IP telephony network
(see

Figure 1-1

). The Cisco VG248 offers 48 fully-featured analog phone lines to

be used as extensions to the Cisco CallManager system in a compact 19-inch
rack-mount chassis.
