日本是世界上VoIP发展较快的国家之一.以传统电话网络IP化为目标,在一开始就将VoIP纳入了已有的管制范围内。管制框架的修改中最重要的是取消了按有无电信设施划分第一类、第二类电信运营商的规定,并在市场准入、退出制度方面取消了许可制,改为登记、报备制,引进了公益事业特权许可制度,并对两种等级的VoIP业务设置了不同的准入规定。但目前VoIP尚未纳入普遍服务的范畴。 Japan is one of the fastest growing countries in the world in terms of VoIP, aiming to put IP in the traditional telephone network into the existing control scope from the outset. The most important thing in the revision of the regulatory framework is to abolish the provisions on the categorization of category I and category II telecom operators with or without telecommunications facilities and cancel the licensing system in terms of market entry and exit systems and replace them with registration and filing System, the introduction of public service privilege licensing system, and two levels of VoIP services set different access requirements. But VoIP is not yet included in the scope of universal service.
