A method of management and control of voice calls and a gateway for the same designed to maintain a real-time characteristic of speech and a constant quality of speech comprising a first step of discriminating whether or not an input packet is a voice call packet, a second step of deciding, when discriminating that the packet is a voice call packet, whether or not the voice call packet can be carried over the transmission path based on both an available band provided in the transmission path and a required band for the voice call packet, and a third step of transferring the voice call packet only when it is decided that it can be carried.
