IP电话声音嘈杂而且延时,因而声誉不佳。如果说对于思乡心切的学子们,低廉的费用使他们并不在意断断续续的话音的话,商业应用却无法容忍这种基于Internet的电话。但无论如何,Voice over IP并不会因此而没有市场。 通过使用租用线路,Voice over IP电话可以提供高质量的国际电话服务,而且费用非常低廉。采用这种技术,跨国性的公司可以通过广域网将分散在世界各地的子公司连接起来,从而使各地的雇员之间可以进行语音通信。 设备制造商则利用Voice over IP技术致力于语音服务中心,通过使用Web技术使用户在进行Web浏览的同时可以与服务中心进行语音交谈。
IP telephony sounds noisy and delayed, so poor reputation. Business applications can not tolerate such Internet-based phones if the low fees mean they do not care about intermittent voices. In any case, Voice over IP does not have no market. Using leased lines, Voice over IP telephony offers high-quality international calling at a fraction of the cost. With this technology, multinational companies can connect their dispersed subsidiaries around the world via wide area networks, enabling voice communications between employees across the world. Equipment manufacturers are using Voice over IP technology to voice service centers, through the use of Web technology allows users to conduct Web browsing at the same time with the service center voice chat.
