This is kinda vague, but I know there is a 'fragment' type command that can
be used when running VOIP to break down larger packets into smaller ones so
that the large packets do not slow down the little ones.
I can't remember the command exactly, its out there on CCO somewhere, but I
remember that it had 'fragment' in it, instead of trying to drop the MTU.
Hope that will help some.
