Is DSL available with voice-over-IP so I can use 1 phone line for voice & data?
True VoDSL (voice over DSL) is currently available from a very limited number of providers: for example, Sprint ION, now in beta-test in various areas of the US. VoDSL seamlessly splits off voice to your phone or phones, taking small parts of the DSL connection for high priority voice packets as you make or receive calls. With any regular DSL line, just as you did with modems, you may download some of the internet to phone type programs such as dialpad. These programs may suffer from various problems – delay, echo, quality loss etc. Dont forget that voice & data can be “on the same line” today if you use ADSL provided by the local telco, and soon with CLECs due to a line sharing agreement, regular voice service and ADSL can run over the same physical copper pair. In this sense, yes, 1 phone line is for simultaneous voice and data. But there is no integration between them.
