Which four devices can be used to provide analog ports, traditional phones, and fax machines? (Choose four.)

The Cisco VG224 is a dedicated 24-port analog voice gateway that provides FXS ports to connect traditional analog phones and fax machines directly to a VoIP or CUCM environment.

A Foreign Exchange Station (FXS) Voice Interface Card supplies dial tone and battery current directly to analog endpoints such as phones and fax machines, making it a valid analog port provider.

The Cisco High Density Voice/Fax Network Module (NM-HDV2) is designed for digital T1/E1 voice trunks, not for FXS analog station connections to traditional phones and fax machines.

The Cisco ATA190 Analog Telephone Adapter bridges up to two analog devices to an IP network, enabling standard phones and fax machines to register with CUCM via SIP or SCCP.

The Cisco VG350 is a high-density analog voice gateway supporting up to 168 FXS ports, purpose-built for connecting large numbers of analog devices to a CUCM infrastructure.

The Cisco Unified Border Element (CUBE) functions as a SIP session border controller for interconnecting IP-to-IP SIP trunks and does not provide analog phone or fax ports.

A Foreign Exchange Office (FXO) interface connects to a PSTN line or legacy PBX to receive an outside dial tone - it is the trunk-side interface and does not provide analog station ports for phones or fax machines.
