The Cisco VIC3-4FXS/DID is a four-port voice/fax interface card designed for compatible Cisco routers. It features four FXS ports used to connect directly to phones, fax machines, and key systems, generating battery polarity reversal and caller ID. It also has one DID port used to provide off-premises DID connection from the central office, serving only incoming calls from the PSTN and not supporting caller ID in DID mode. The card supports industry-standard codecs like G. 711 and G. 729a/b for high-quality voice communication over IP networks. It uses standard RJ-11 connectors and has a modular form factor for seamless integration into existing voice gateways and telephony infrastructures. It supports up to four concurrent inbound or outbound calls, one per FXS port, assuming sufficient router CPU and DSP resources. The card supports FSK and DTMF caller ID between the first and second ring on North American and many international PSTN networks.
