That is a HUGE issue. We've been TRYING to use different flavors of IOS and
we've been finding lots of bugs (specifically with ISDN). We've also tried
using 12.2, but that's been even worse. Hopefully they'll come out with a
stable IOS for 2500 series in the 12.1 code (or maybe in the next release of
12.2). The (T) flavors seem to be more stable than any of the others.
We've been using 12.1.5T10 (c2500-jos56i-l.121-5.T10.bin) but like I said,
we've been having some serious issues with ISDN.
thanks,
