I don't know what you've done for your smaller deployments. Different
people have different opinions.

My personal preference, if this is United States:

DS3 -> Adtran channel bank, break out PRIs
PRIs -> multiple Cisco PRI->SIP appliances. A 3845 maxed out can do 24
PRIs. I recommend using two and splitting load for capacity /
failover.
Using pure SIP between the gateway appliances and at least two
asterisk boxes for flexibility and failover-ability.
