We use the Cisco AS5400 in which you can enable/disable any option as you see fit using resource pooling. We use it to support KFLEX modems which fail to connect properly w/ the v.92 tones. The way it deterimes which settings to use is based on called station id. We also find modems that try to to retain to highest speed tend to reach the limit and drop the connection. Most of our customers are in rural areas w/ poor quality phone lines. We found it was easier to create resource groups to lock people to 21000 baud via setting their connection number than giving the customer init strings to limit the connection that way. Sure there are probably better solutions, but this has solved nearly all connection problems we've seen. I realize you may end up not using cisco, but I'll include a small example just in case it's useful to anyone.
