VoIP (Voice over Internet Protocol) networks require an 8-Port FXS Gateway device in order to link analog devices like phones, fax machines, and outdated PBX Systems with modern IP-based communication systems. The ports on these gateways enable the smooth integration of digital and analog communication systems. Using an 8 Port FXS Gateway to switch to VoIP networks significantly lowers telecom expenses without sacrificing functionality. It becomes important to set up more devices as call centers expand.
