Largest deployment?

We are looking to deploy asterisk in a large enterprise. I am wondering what is the largest deployment out there. I am interested in hearing about sites that have mulitiple units with more than a 1000 users. Thanks.

Sam Houston University is switching 6000 handsets.

We did an implementation with about 1700 end users and several locations in the Netherlands. If you need more inforation, please contact R.E. van Leyden, pm me for more information.

We run a large scale network which consists of about 15 asterisk servers and a couple of Kamailio (OpenSER) gateways. We transport multiple thousands of simultaneous sessions inbound and outbound.
