Don't Need Special Software

With the Nokia E70 -- it's got a sip dialer already. The problem is finding a wifi network where you want to make a call. If you could get it going at home and office that'd be plenty for a lot of people. I still need to investigate the possibility of connecting to my home asterisk server through T-Mobile's unlimited data service, either directly from the cell or by installing asterisk on the laptop and connecting to the Internet through the phone's bluetooth modem and then running an ad-hoc wifi network on the laptop. That would be sick! I'm not sure their data service provides enough bandwidth to run a voip call, but it's a neat idea.

I thought of that before. Usually, those cell-network-based data services have a special clause in the contract forbidding VOIP use. :(
