- Four FXO ports in single slot
- Direct router integration
- Unified configuration interface
Universal Compatibility
Supports multiple regional telephony standards through configurable parameters, making it suitable for deployment in various geographic locations with different analog signaling requirements.
- Configurable for regional standards
- Broad platform compatibility
- Flexible deployment options
Deployment / Use Cases
The Cisco VIC2-4FXO-RF is designed for organizations requiring analog telephony integration within their Cisco router infrastructure. Typical deployments include connecting to PSTN lines for outgoing calls, interfacing with legacy PBX systems, or providing failover connectivity for VoIP systems.
This card is particularly valuable in branch office scenarios where Cisco routers serve as integrated voice and data platforms. The four FXO ports allow for multiple analog line connections, supporting basic to moderate voice traffic requirements without the complexity of separate gateway appliances.
Branch Office Voice Connectivity
Enables small to medium branch offices to maintain analog telephone connectivity while implementing VoIP systems, providing flexibility during migration periods or for specific analog-only applications.
PSTN Gateway Functionality
Serves as a gateway between VoIP networks and traditional public switched telephone networks, allowing VoIP systems to place and receive calls over standard analog telephone lines.

FAQ
What type of ports does the VIC2-4FXO-RF provide?
The VIC2-4FXO-RF provides four FXO (Foreign Exchange Office) ports with RJ-11 connectors. These are analog telephone interfaces designed to connect to standard telephone lines or PBX systems, enabling voice communication between VoIP networks and traditional analog telephony infrastructure.
What is the difference between FXO and FXS ports?
FXO (Foreign Exchange Office) ports connect to telephone lines or PBX systems, receiving dial tone and ring signals from the telephone company or PBX. In contrast, FXS (Foreign Exchange Station) ports connect directly to telephones or fax machines, providing dial tone and ring voltage. The VIC2-4FXO-RF provides FXO ports for connecting to external telephone lines or PBX systems.
Can this card be used for both inbound and outbound calling?
Yes, the VIC2-4FXO-RF supports both inbound and outbound calling through its FXO ports. When configured properly within a compatible Cisco router, it can receive incoming calls from analog telephone lines and place outgoing calls to the PSTN or connected PBX systems, functioning as a bidirectional voice gateway.
What does 'Universal' mean in the product name?
The 'Universal' designation indicates that this FXO interface card supports configurable parameters for different regional telephony standards. This allows it to be deployed in various geographic locations with different analog signaling requirements, making it adaptable to different country-specific telephone system standards without requiring hardware modifications.
