cjm, you are wright, I can use more than one machine ...
I have two machines designated for that but I wanted to put in one isdn pri car and in another isdn pri and analog card with fxo moduls. That way I have 30 lines with isdn in one machine and 30 isdn and 10 analog lines in another witch is better balansed than one machine with two isdn (60 lines) and another one with analog (10 lines). I could buy one more machine (like you sad, used dell) and put 3 machines ... but I want to try this way first ...
