If you're referring to T-Mobile's "[EMAIL PROTECTED]" service, it's actually $20 per month, per line on the account (unless it's changed very recently). As far as how it works on T-Mobile, I recently had some questions answered by them about that.. They use UMA over wifi, and it does automatic switching between the wifi and the gsm towers (ie; your call stays up). Quote from the tech I talked to: "[EMAIL PROTECTED] does not use a VoIP protocol, as the voice data is transferred from the Internet directly to our UMA Gateway and then through our regular Mobile Switching Centers." Pretty interesting stuff. -- Jason Parker Digium _______________________________________________ Sign up now for AstriCon 2007!
