The object of the invention is to improve the voice quality during the transmission of voice over the Internet. A gateway is disclosed in which the packet length to be transmitted is varied as a function of the spatial distance and/or time distance of the called party from the caller. Different geographical service areas, such as local call, trunk call up to, e.g., 100 km, trunk call above 100 km, or local call, regional call, long-distance call, and/or different time ranges, e.g., time delay 30 ms, 50 ms, 100 ms, are introduced. On the assumption that local networks are less loaded than global ones, voice calls in the local area are assigned long packet lengths to optimize the bandwidth utilization and thus improve voice quality, and voice calls for long distances, where increased interference may occur on the long transmission link, are assigned short packet lengths, thereby increasing the throughput of voice data packets and thus improving voice quality.
