I'm using freetalk. It's similar to Vonage in that you plug a DTA into your broadband connection. Both services' DTAs are locked to the respective service (which is no big deal). If you're connecting to broadband through a modem-router, the freetalk device really is "plug and play". Also, you don't need your PC switched on (unlike using a USB phone or a headset plugged into your PC). I've found the freetalk service to be very good - no change since I bought it some months ago. Most people don't know I'm using VoIP when I call them wth it. Cheers, Dan
