We're doing 400 CPS on a system at the moment.

Load balanced across Asterisk machines, and load balanced across 
provider's machines.

MySQL is the hardest thing to get working, and requires splitting of

Whole system is split into blocks which each for part of a redundant system.

One of the problems was lack of randomisation of numbers - you can take 
out a telephone exchange pretty easily if too many calls go to one place.
