[cisco-nas] Is 12.3 (10c) OK for dialup only (no voice).

Just looking at the configuration will give us no clue why you are
experiencing disconnects. But to answer the question in the subject:
Yes, 12.3(10c) is successfully deployed in some large dialup
environments..

So we'd need to know what type of "disconnects" you're getting? Modems
suddenly dropping? Problems establishing the call (including PPP/Radius
issues)? 
http://www.cisco.com/warp/public/112/chapter17.htm provides some
guidelines you might want to follow to narrow down issues..

P.S: Looking at the config, I'm wondering why you disabled CEF on some
interfaces?
