Let's just say that you shouldn't have trouble with four E1 lines in 
this system (as long as you have a hardware echo canceler).  Even with 
software echo can, this hardware is overkill.

I'd suggest getting the slowest processor available new (At least 1.5Ghz 
for AMD Athlon/Opteron and 2.xGhz  for Intel P4/Xeon) and get redundant 
power supplies, ECC memory, RAID 1 or higher and a nice UPS.

You may also think of looking at used previous generation high-end 
equipment.  It still has all of the good engineering and redundancy, it 
just isn't new and in many cases you don't need the latest speedy 
equipment to handle the load.  In many instances, the same money spent 
buying used high quality equipment will give you more reliability than 
buying cheap new equipment.
