Iirc a long time ago there was a discussion about load testing by 
playing MoH was not a realistic test. Something about all MoH music 
getting streamed synchronized so basically Asterisk only has to stream 
one file and sorta multiplex that single output to all the established 
calls (legs).

The difference (13500 with MoH versus 330 with a real dialplan) shows 
that it makes sense to mimic your dialplan in your test scenario as much 
as possible to see how far you can realistically push the box and still 
keep things stable and sound quality good.
