Core Product Positioning
The Cisco VIC2-2FXS is a second-generation pluggable analog voice daughter card designed for Cisco multiservice integrated routers. FXS ports supply line battery, dial tone, ringing voltage and signaling to directly connect analog end terminals. This module enables enterprises to deploy analog voice and fax services over IP WAN networks, supporting VoIP gateways, SRST, Cisco Unified Communications Manager Express (CUCME), toll bypass and branch analog telephony connectivity. It serves as the analog station interface for basic telephones, fax machines and PBX station ports.
