You want to allow a traditional telephone handset to operate as an IP phone on a Cisco network.
Which of the following Cisco devices would accomplish this task? (Select the best answer.)

A.
ATA 190

B.
High Density Voice/Fax Network Module

C.
CUBE

D.
FXO Voice Interface Card

Explanation:
A Cisco Analog Telephone Adapter (ATA) 190 would allow a traditional telephone handset to operate as an IPphone on a Cisco network. The ATA 190 enables you to connect a traditional telephone handset to an Ethernet
network. It houses two RJ11 traditional telephone ports and a single RJ45 Ethernet port. It is possible to
connect both a traditional handset and an analog fax machine to the RJ11 ports. On the network, the ATA 190
behaves similarly to a normal Cisco IP phone.
Other Cisco IP telephony devices that can support analog ports for traditional handsets and fax machines
include the Cisco Foreign Exchange Station (FXS) Voice Interface Card, the Cisco VG 224 Analog Voice
Gateway, and the Cisco VG350 Analog Voice Gateway. The FXS Voice Interface Card is an expansion card
that enables a Cisco IP device to connect to RJ11 equipment.
The Cisco VG224 and the Cisco VG350 are both analog voice gateways. Each of them is capable of
connecting traditional analog telephony devices to a Cisco Voice over IP (VoIP) network. The VG224 is an older
gateway that supports 24 analog FXS ports and two Ethernet ports. The VG350 is a newer high-density
gateway that is intended to connect traditional analog telephony equipment, including voice and fax, to an
enterpriselevel voice network.
The Cisco Unified Border Element (CUBE) is a device that connects Cisco VoIP networks to service provider
Session Initiation Protocol (SIP) trunks. Therefore, CUBE does not support traditional analog telephony
devices.
A Foreign Exchange Office (FXO) Voice Interface Card enables a Cisco voice router to connect an RJ11
analog telephony device to the public switched telephone network (PSTN) or to a private branch exchange
(PBX). It does not enable traditional telephony devices to participate on a Cisco VoIP network.
The High Density Voice/Fax Network Module is an expansion for Cisco voice routers. This module supports
only analog voice devices, not fax devices.
