As long as your machine is at least a single CPU, 2GHz or better, you should
be fine with the software encoder.  The TC400 is really only necessary on
systems where the transcoding load alone would overtax the CPU.  It's really
difficult to estimate a good number of where you should start considering the
TC400, because there are so many other tasks where the CPU may be required
and would affect the overall result, but the number is probably somewhere
north of 40 simultaneous calls.

I'm sure somebody will chime in and say they're using 100 simultaneous calls
on the software encoder alone.  As I said, the number is extremely fungible,
based upon what else the CPU is doing.
