Well, I guess I need to find that description of how it works. I'm surprised I didn't bookmark it since it reminded me of the Ericsson deal and got me to wondering whatever happened to their project that did the same thing. That was when I found their press releases had disappeared. If you're online either you need to have your line "forwarded" or tagged in some other way such that it knows you're online instead of just "on the line". Next you have to deal with the fact that 90% of the ISPs do not assign everyone a specific IP address, you're merely dynamically assigned any free number out of the pool each time you connect. Anyhow, a regular voice call headed for you while you're online will have to be routed to your ISP on a free incoming POTS line and it will have to carry the information as to who it is supposed to be for. Now the ISP (or someone) has to take that call, convert it to IP voice and aim it at the address you're using. You'll have to have a DSVD or perhaps just a voice modem as well as some additional software running at home. If I recall Ericsson was going to handle the voice utilizing a variation of their CDMA wireless technology. Voice compression is a tricky matter and I have a feeling that it would take quite a while for anyone to equal the quality that Data Race's 100 or so software engineers have come up with after working well over a year on it. I believe we're running a proprietary complex code variation of CELP. I'm sure many will enjoy this short page on voice compression: att.com and I know a lot of people will have great fun with this: sipro.com Incidentally, I checked my dialer connection stats and it's a good night, I'm only running around 2.8% frames lost. I wonder if DR would be interested in putting something like that on their website? Nah, it's going to be too easy to have a real-life demo.
