I've tried dialer callback-secure before and it didn't make a difference.
I just tried these IOS combinations (I'm runing these on 3640 and they are
enterprise plus version)
11.2(26p4) -- calling --> 12.1(16) worked
12.0(23) ---- calling --> 12.1(16) worked
12.1(2) ----- calling --> 12.1(16) worked
12.1(7) ----- calling --> 12.1(16) worked
12.1(10) ---- calling --> 12.1(16) worked
12.1(11) ---- calling --> 12.1(16) failed
12.1(12) ---- calling --> 12.1(16) failed
12.1(16) ---- calling --> 12.1(16) failed
12.2(10a) --- calling --> 12.1(16) failed
In any case, initial call works fine but callback from 12.1(16) fails.
Could this be a bug in IOS? I looked at cisco site for bug report but
couldn't find one.
