For this size, I'd definitely recommend a clustered architecture. You could use a set of Asterisk machines doing VoIP <-> T1 bridging, along with call routing, billing, etc, and a set of SER/OpenSER machines in front to distribute calls between then. For example, see the diagram half way down: http://integrics.com/products/enswitch/guides/latest/en/system/architecture/ (with many more Asterisk machines of course). Some of our larger Enswitch customers are within the call volume range you mention above (though the larger systems tend to be SIP only as 25 to 250 Digium cards and the machines to run them in start getting expensive), and running very happily on this architecture.
