Switching telephone providers used to be the only way homeowners could save money on telephone bills. Now thanks to new technology, comsumers have another choice-making phone calls over the internet. And this can be completely free if you call another person with an internet phone set-up. The technology is called voice over internet protocol  , 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   voice quality, consumers can save a fortune chatting for free to other internet phone owners and save money calling regular landlines  . But, as the saying goes, . Many of these services suffer from uncontinuous lapses   in quality. While some users may tolerate echoes or a dropped call, improved quality is needed to attract more customers.
