I remember hearing University of Pennsylvania have been using Asterisk
for sometime. I am not certain where I came across that information,
but google confirmed it as a fact. And you may need to ask for more
details from Digium as they worked together, or call the school. I am
relatively certain they would share their experience. The deployment
was of 15,000 extensions, just about what you have in mind. Below is
some articles.
