Cisco VIC3-4FXS/DID Network Voice Interface Card VIC34FXS/DID

Description:

The Cisco VIC3-4FXS/DID Voice Interface Card is used in Cisco Integrated Services Routers to provide analog voice connectivity for telephony systems within enterprise and branch office communication networks. Commonly installed in Cisco ISR platforms, this interface card supports four FXS or Direct Inward Dial (DID) ports, enabling routers to connect analog telephones, fax machines, or PBX systems to IP-based voice networks. Maintenance teams and telecom system integrators use this voice interface card for deploying voice gateway solutions, integrating legacy analog devices into VoIP systems, and replacing existing voice interface modules in Cisco router environments.

Applications:

The Cisco VIC3-4FXS/DID interface card is commonly used in enterprise unified communications environments where analog telephony devices must be integrated into IP-based voice networks. It allows Cisco routers to function as voice gateways that connect traditional telephones, fax machines, and PBX systems to VoIP infrastructures. The card is widely deployed in corporate offices, call centers, healthcare facilities, educational institutions, and government networks where legacy analog communication equipment must operate alongside modern IP telephony systems.
