[cisco-nas] Best General Purpose IOS for AS5800 doing Dial-up & ISDN

[Michael L. Hardrick]

What's the Best General Purpose version of IOS for the AS5800.
We've run into some issues with our old 7206VXR and had to
replace it, so we are looking into changing the IOS at the same
time.

We don't necessarily need V.92, but would like system stability
connection performance, and lastly modem speed.

Any suggestions??
