   A few Asterisk boxes supported by a proxy should be able to handle
that in terms of transcoding and call volume alone.  Where the limitation
is going to be terminating 200 TDM calls at once.  That would be 8.69 
PRIs.  You might be able to swing it with Asterisk and PCs and quad-span
T1 cards, provided they can actually operate concurrently in practice as
well as advertised in theory, without lockups, etc.

   Otherwise, some sort of outside media gateway like a Cisco AS would be 
your ticket.  Cheaper solutions available also, but I do not have much
familiarity with these.
