A Google search for

	"first call" 2673

found:

	http://www1.firstcall.com/support/client/support1.shtml?support%7Cclient%7Cproduct

which says:

	First Call for Windows 4.2

	     o First Call for Windows 4.2 software is provided for our
	       customers who have a First Call 4.2 User ID&
	     o Please use port 2673 if possible, but port 8000 will continue
	       to be accessible over the internet. 

It's probably referring to some software called "First Call for Windows
4.2" that uses the port in question.

Reading more stuff on the site to find out what that software is, and
does, is left as an exercise for the reader.
