Sean,

Thanks for your response.  I'm going to take a look into OpenSSI.  It'd 
be amazing if it ran Asterisk without any side effects.

I've addressed the number of threads that Asterisk uses in my first 
follow-up post.  In short, the answer is yes because it uses a 1 thread 
per call model.

Thank you,
