I had a friend in St. Paul that couldn't accept incoming connections for game hosting. Called AT&T, they wouldn't help us. We weren't supposed to be doing that. Apparantly AT&T wants us to use broadband for just Web surfing, instant messaging, and email. Email and Instant messaging are both low bandwidth. HTTP is tons of small connections bursting every so often (you take time to read the web pages) and is easily cacheable. (Lots of people going to yahoo,cnn and such) Everyone isn't retrieving data at the exact same time. These support their profits quite well. They dump a ton of users on a smaller pipe, pretending to give the all this bandwidth. Then, when they really want it (like broadband SHOULD be used) they create a big stink. Think about the things they don't like: VOIP (with Vonage apparantly) VPN's GAMING servers All things with constant high bit rates. > > > >>I did speed test with their online speed test and I was >>getting 814 Kbps >>down, 184 up. >> >> > >Vonage uses the g711 codec, which takes up 64kbps.

It may have a difference depending on the quality of of your phone. Seriously, I would say with bandwidth is important for VOIP, but its easy to obtiain (64kbps is uncompressed basically). Its harder to get the latency low enough so that it doesn't seem like your are talking to someone in Russia or China (or any place far away). >Jay >_______________________________________________ >Twin Cities Linux Users Group Mailing List - Minneapolis/St. Paul, Minnesota >http://www.mn-linux.org >tclug-list at mn-linux.org >https://mailman.mn-linux.org/mailman/listinfo/tclug-list > > >
