Anyone running Enswitch for a start. If they're running a 6 machine 
cluster or larger, they'll have a pair of failover SER or OpenSER 
machines delivering calls to a set of Asterisk machines which do the 
call routing, features, and billing. All telephony machines then read 
their configuration from a pair of replicated/failover MySQL machines. 
On the larger systems (1000 concurrent calls and up), some functions 
such as the web, NAS, and conferencing are split off onto dedicated 
machines. For am overview of the cluster architecture, see:

Systems are in production today with over 100000 users and thousands of 
concurrent calls at peak load. More links at the bottom of:
