672 eggs in 1 basket doesn't sound like a good plan to me.

It's a bit out of my league (300 is my biggest installation so far), but 
I'd suspect dedicated hardware like something from Cisco or a used Ascend 
TNT to take the DS3 in 1 side and spit SIP over Ethernet out the other 
would be a good starting point.

Send the SIP calls out to a couple of OpenSER/OpenSIPS/Kamailio servers 
talking to several (like 4+) Asterisk servers.

This way you can take individual servers out of production without 
disrupting everything at once.

My "300 concurrent call" project was taking SIP calls from a Tekalec 7000 
talking to 4 hosts. Each host ran OpenSER on port 5060 and Asterisk on 
port 5061. The client loved the flexibility.
