v.92 Support in Linux?

cswiii asks: "Recently I was in the market to buy another modem. I'd not done this is a few years, and so there were a few new improvements about which I had to learn. One of those things was v.92, which, among other things, allows the user to keep the connection alive, should s/he get another call. This requires software on the user's part; my Sportster came with Windows software. However, a cursory check on Freshmeat for 'v.92' returns nothing. Is there any Linux development currently going on to support v.92?"
