Any of the Atom CPU systems will /easily/ handle 25 concurrent calls 
(and with a 25 extension system, 25 concurrent calls is very unlikely). 
  I use the single core Atom 230 CPUs for systems of this size. 
Something to bear in mind is how the system will be used, max concurrent 
calls isn't really that great a performance factor, call arrival rates 
are more relevant, the CPU time is spent setting up and tearing down 
calls.  Simply having calls in progress with no transcoding uses a tiny 
amount of CPU in comparison to the work involved setting up and routing 
a new call.

cheers,
Paul.
