Cisco VIC-4FXS/DID Interface Card

Overview :

The Cisco VIC-4FXS/DID is a 4-port analog voice interface card designed to support both Foreign Exchange Station (FXS) and Direct Inward Dialing (DID) connectivity. Installed in Cisco routers, this module enables voice communication over traditional analog lines, making it ideal for small businesses, branch offices, or legacy telephony integration. Each port can be configured for either FXS or DID functionality, allowing for flexible deployment depending on communication needs. FXS ports are commonly used to connect analog phones or fax machines, while DID ports receive calls from the public switched telephone network (PSTN) directly to internal extensions. This card delivers reliable voice features and seamless integration into Cisco Unified Communications environments, allowing organizations to retain analog lines while benefiting from modern VoIP infrastructures.
