Fax and Modem Connectivity
The Cisco VG 224, Cisco VG 204 and Cisco VG 202 support fax machines and modems. When
using fax machines, they support 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, Cisco VG 204
and Cisco VG 202 and will be transferred over the network using modem passthrough.
