Netopia said it has created a voice over Wi-Fi phone certification program: The program will certify that voice over Wi-Fi phones interoperate with Netopia's VoIP gateways. This is fine for Netopia, but doesn't guarantee that such phones will interoperate with gateways from any VoIP gateway.
The CNET reporter who wrote this article could afford to think a bit more critically rather than buying hook, line, and sinker everything companies tell her. The story reads like an advertisement for voice over Wi-Fi. She says here: "Some experts predict that cordless Wi-Fi phones could eventually replace cellular phones." I'd love to know who those experts are. Wi-Fi is a local area networking technology and it's ridiculous to imagine that it would ever cover the same amount of area as a cell phone network.
