To further support native vs mpg123 here is something from astertest.com
- admittedly its old and may no longer be valid, but it should be useful
for a reference ...

22/11/2004: Music On Hold Part 1.
Today we reached 361 simultaneous SIP uLAW Music On Hold channels on
that same 350$ machine.  When using GSM we got up to 173. Out of
curiosity we tried some optimized configs with anthm's music on hold
native format patch and got to 395 channels, regardless of the codec
used. We are currently investigating more ways of increasing that value.
(As we think it should scale higher than app_playback). is that what you
were talking about?
