The full form of IGW is International Gateway.
An International Gateway (IGW) serves as a crucial connection point between a country's domestic network and the rest of the world's telecommunications networks. It handles international voice and data traffic. For example, as the provided reference illustrates, an IGW operator is expected to route international calls through the Interconnection Exchange (ICX) to ensure proper handling and billing within a country's telecommunications infrastructure. This prevents bypassing regulations and ensures fair competition among Access Network Service (ANS) operators.
