I use a Zoom internal DSL modem, which uses the Conexant chipset and behaves in a similar way. The icon is labelled Zoom PPP DSL in my case.
I found no way to change it, even through the registry, so my advice is to live with it. I did.
You'll get used to it, and it's a good modem, with none of the glitches that can sometimes befall USB modems.
