摘要
虽然VoIP业务越来越普及是不争的事实,但关于其用户群、使用规模和使用目的一直众说纷纭。为此,作者长时间观察中国电信的国际链路,积累了大量有价值的数据,并发现H.323、SIP仍是VoIP的主要协议,其规模已经接近传统电话,主要用于工作联系,而Skype则更偏向于个人通信。
Though it is an undisputed fact that VoIP is more and more popularized, the opinions have always been diversed and confused with regards to VolP＇s user groups, scale of use, and its applications. For this reason, after observing international links of China Telecom for a long period of time, the author has accum^ated large volume of valuable data, and has discovered that H.323, SIP whose scale has already approached the same as traditional telephone are still the main protocols for VolP and are mainly used for communications at work, while Skype is preferred for individual communications.
