I believe the tradeoff is that though it's compressed it uses a bit more
bandwidth and a bit more CPU.  Because of the redundancy to remove chop,
it has greater overhead on almost all counts.  I have no issue using it,
and frequently use it for asterisk <> asterisk trunking where bandwidth
is insufficient for uLaw.
