VoIP Gateway

A network device that converts voice and fax calls, in real time, between the public switched telephone network (PSTN) and an IP network. The primary functions of a VoIP gateway include voice and fax 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.

The gateway is used in a variety of ways that include connecting an internal telephone to an external game, connecting a PSTN interface to a telephone network, and connecting PSTN and VoIP interfaces externally.
