were those people running g.711 or something using less bandwidth?

And why are you thinking CPU cap?
What is the load average (from top or uptime)?
In top** (after pressing 1) are you seeing processors that are not idling or are in large wait states?
[purpose of these questions is to either get information for us to understand that you have a CPU
problem, or point it out to you that you don't]


** there are better applications than top for seeing where the processors are spending their time,
but my brain is mush for remembering them right now.
