You might find that a decent USB handset makes your reluctant users  
happier to use
a softphone. Often the objection is about the 'feel' of the thing.

Also Tesco (and Freshtel) have some IAX devices.

If you really want to put together a SIP to IAX proxy, then a simple  
asterisk config would do.
(You might want to look at Freeswitch or Yate , as their Windows  
support is a little more
'enthusiastic' than Asterisk's :-) - they both support IAX and SIP )
