Gavin -
   The short answer is yes, this is possible, and is done quite  
often.  How exactly you configure it is of course the trick - there  
are many possible different methods by which you might accomplish this  
feat, depending on what your existing resources are and what your end  
goal is.  T1? PRI? H.323?  You may consider IAX2 for trunking and save  
a lot of bandwidth as compared to SIP, if bandwidth is a concern.  If  
you're using T1 or PRI, you'll need a hardware card to do this.

   I'd start with setting up a basic Asterisk server from source and  
getting two SIP phones working on it.  I'd not suggest using one of  
the GUI-enabled versions - that may be more layers of stuff than   
you're looking for given your stated goal.  Figure it out, read the  
O'Reilly Book (Asterisk: The Future of Telephony) and you'll probably  
figure out fairly quickly how to use Asterisk as a black-box trunking  
interface for your systems.
