Specifications

   Product Overview:
  • The Cisco VIC-2FXO is a 2-port Foreign Exchange Office (FXO) analog voice interface card, designed to connect Cisco Integrated Services Routers (ISRs) to the Public Switched Telephone Network (PSTN) or a PBX system. Each FXO port connects to a standard analog phone line, allowing routers to make or receive calls through the PSTN.
  • This interface card is ideal for small to mid-sized businesses, branch offices, or any deployment requiring legacy analog telephone line access alongside modern VoIP infrastructure. The VIC-2FXO is plug-and-play compatible with various Cisco ISR platforms, offering reliable performance, easy configuration, and consistent voice quality.
  • Whether used for local emergency fallback, analog fax machines, or small office trunks, the Cisco VIC-2FXO is a cost-effective, secure, and stable solution for hybrid telephony environments.
