BroadvoxDirect $19.99 Unlimited usage for all North Americsan exchanges, with all calling features (plus a second number in the same or different area code) and no tax. At least no tax for me because I'm in Canada and they're out of a specific state. Very well-prices long distance for the rest of the world too.

The biggest thing to be careful about is QoS (Quality of Service) management on your network. If you follow their instructions and connect the ATA to your modem and the rest of your network behind it, there shouldn't be a problem. It handles QoS and doesn't do Double-NAT (I was worried about this at first and went with a different configuration). If you connect the ATA after your broadband router then you really have to make sure you have QoS on your router. Otherwise other traffic over the router *WILL* interfere with the voice packets.
