[Asterisk-Users] quad t1 / 1U rack server combos

[Cory Andrews]

William - You should take a look at the foneBRIDGE, new product from 
redFONE.  It has (4) PRI interfaces, and you run our to your primary and 
failover Asterisk servers via Ethernet.  It does not do load balancing. 
but if you have a hardware failure in your primary Asterisk box, you can 
just fail right over to your secondary box.  You don't need any PRI 
interface cards in your Asterisk host server at all.
