The Cisco VG350, VG224, VG204XM, and VG202XM support feature access codes (FACs) in conjunction with

Cisco Unified Communications Manager and Cisco Unified Communications Manager Express. Refer to

documentation for these applications for details.

Fax and Modem Connectivity

The Cisco VG350, VG224, VG204XM, and VG202XM support fax machines and modems. When using fax

machines, they support Cisco Fax Relay, T.38 fax relay, and fax pass-through. Cisco and 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 VG350, VG224, VG204XM, and VG202XM and are transferred over

the network using modem pass-through.
