[Freeswitch-users] Opus codec issue

If you could actually measure it, I'm fairly sure it won't matter and I'm
pretty sure a codec like OPUS wouldn't be one that you could record native
due to stateful information being in the bit stream.  The time its taken
for us to exchange these emails is many times more than it would cost you
to play the wav files in the first place.  I think G722 may suffer the same
problem.
