Cisco VIC-2FXS 2-Port Voice Interface Card with Dual FXS Ports

With voice/fax network modules, the Cisco multiservice access routers offer unparalleled multifunctional capabilities in a branch office solution, building on Cisco's strengths in LAN-to-LAN routing and dial access. The voice/fax network modules for the Cisco multiservice access routers enable packet voice technologies including VoIP and VoFR. Cisco's voice solutions provide the means for integrating both voice and data within a single network and allow users to take advantage of services, such as toll-bypass, without sacrificing voice quality. This combination of voice solutions leverages Cisco's proven track record of being able to effectively handle time-sensitive traffic, such as Systems Network Architecture (SNA) over IP networks. Cisco IOS software also incorporates built-in quality-of-service (QoS) features along with standards-based (FRF.11 and FRF.12) encapsulation and fragmentation providing efficient transport of both voice and fax over IP and Frame Relay networks
