ZDNet India : Communication breakdown threatens VoIP in the U.S.:
"As cable and telephone companies begin offering Net telephony services to U.S. consumers in earnest, complications on the back end threaten to crimp cost savings for providers and ultimately dampen expectations for the much-hyped technology. "

Currently, about 11 percent of all phone calls use VoIP at some point in the connection, with some analysts forecasting a US$10 billion a year business for broadband providers selling a majority of the world's phone calls. Most of this VoIP shuttling takes place in delivering international calls, through IP network providers such as iBasis and ITXC. Calls are handed off to traditional circuit-switched networks at either end, but make long-distance jumps using cheaper packet switching, or IP, technology.
