In our setup we tried to use a 4 Port T1 card in a Compaq proliant. We had no issues with processor load or dropped calls but major echo problems. I figured that since I was using a PRI it was digital and should have no echo issues....I was wrong. I had just as many problems with my pri's as I had with fxo ports. I tried everything to clean it up. Went with a Cisco 5400 and haven't had any issues at all. The unit works like a champ. The unit new with 4 T1 ports is $12K ...where did you get 40K from ?
Another option is to put in an echo can (DITECH) in front of the digium card. I haven't tested this yet ...
