The VIN-812P Gateway is designed as a compact, high performance, and low cost VoIP Analog Terminal Adapter (FXS Gateway).It comes with one FXS port to interface with a traditional analog phone set or a PBX trunk line for VoIP communications. By connecting a PSTN line to the Bypass port, the phone set connected to the FXS port can also access the PSTN line for traditional telephone service. The VIN-812P is a full featured FXS gateway and is designed for easy installation and configuration. It is an ideal low cost solution for travelers and SOHO or SME users.
