Your system should be able to handle that volume easily.

What are you using for PSTN connectivity? 

I have heard of people having issues with Hyperthreading.  That could be 
a problem, although I have never had any issues myself. 

What does top look like? 

When I had a similar issue (voice quality while running monitor on over 
seventy calls) I found a small Linux CLI app, I cannot remember the name 
of it but it would give IO stats (I think it may be named IOStat or 
something similar) and I could see right where the bottleneck was 
(obviously disc IO but I was able to see exactly where the breaking 
point was).  That may help identify something.
