Switching telephone providers used to be the only way homeowners could save money on telephone bills. Now thanks to new technology, sumers have another choice-making phone calls over the internet. And this can be pletely free if you call another person with an internet phone set-up.
The technology is called voice over internet protocol (协议), or VoIP. In 2005, consumer demand for VoIP dramatically grew. In the US, where popularity has grown faster than here in the UK, 8.4 million are predicted to subscribe this year. For the past couple years, VoIP pioneers such as Skype have accounted for the majority of internet phone subscribers.
VoIP is attractive to consumers because it’s cheaper than traditional phone services. With the basic equipment of PC, microphone and headset, and VoIP software and broadband internet for optimum (最适宜的) voice quality, consumers can save a fortune chatting for free to other internet phone owners and save money calling regular landlines (通讯电缆). But, as the saying goes, you get what you pay for. Many of these services suffer from uncontinuous lapses (失效) in quality. While some users may tolerate echoes or a dropped call, improved quality is needed to attract more customers.
Computing has examined the benefits of using a PC as a telephone with VoIP in how easy they were to set up, how effective they were and the range of their features.
Skype(www. skype.) came top for its bother-free approach, easy set-up and exceptional voice clarity. Sipgate (www. sipgate. co. uk), MSN(www. messenger. msn. co. uk) and Yahoo! Messenger (uk. messenger. yahoo. ) provide an audio “wizard” that improves sound levels. Google Talk (www. google. / talk) was less helpful and Babble. net (www. babble. net) was let down by its poor help files. Yahoo! Messenger provides some of the best features, including the option of landline calls, webcam chats, instant messaging, voice-mail and conference calls.
