IP Gateways - Connecting IP to traditional phone systems

An IP gateway is a device that connects an IP network to the Public Switched Telephone Network (PSTN). Typically a gateway will have four or more FXO or FXS analog ports or 1 - 4 digital T1/E1 ports
as well as Ethernet connectivity.

The primary function of an IP gateway is to bridge analog or proprietary digital phone equipment to IP networks. Responsibilities of an IP gateway include compression/decompression, packetization, call routing, and control signaling. Additional features may include interfaces to external controllers, such as Gatekeepers or Softswitches, billing systems, and network management systems.
