GOIP: GSM VoIP Gateway—What It Is and How It Works

Convert SIM cards into SIP lines for your PBX and Save on cell phone calls.

A GOIP is a GSM/VoIP gateway: a device that connects cell phone SIM cards to your Internet voice network (SIP). You insert a SIM card, and those cell phone calls go in and out of your telephone exchange like normal lines. It is used to end calls to cell phones by paying a cell phone bill (which is much cheaper) and to provide GSM lines to your PBX without having to run cables.
