 app_meetme transcodes all media to SLINEAR to mux it through the
psuedo Zap channel for conferencing and this is why codec translation
is taking place. It does this to accomodate multiple participants
coming in with the different codecs, and also because Zaptel itself
operates with media that is very near SLINEAR.
