* The E1 cards have been fine for us. The only issue ... I wrote to him seperately ... I believe he is saying that he wants to do both R2 and ISDN PRI inbound trunks. I know we had to buy hash code for the "other" when we had one of those two. Then I think I remember discovering that you couldn't do R2 and ISDN PRI e1's on the same E1 card. Which means adding another E1 card. (correct me if I am wrong there).
