I dunno...  I know you can terminate 192 concurrent calls (eight T1s) in a 
dual P4 Dell system, 60 calls is less than 1/3 of that.  I realize that this 
doesn't scale linearly and that it also depends on what you're going to be 
doing CPU-wise...  If you're doing external echo cancellation and limiting 
your transcoding (stick to ulaw or something "light" on the CPU) I could see 
sixty concurrent calls on smaller hardware.  DTMF detection isn't all that 
CPU intensive.

You do, of course, need to test to know for sure.  There are far too many 
factors to "armchair quarterback" this kind of decision.  :-)
