Do you have some sort of IP connectivity between the sites? 400 yards is a 
too long for copper cat5, but can be done with fibre, wireless or 
free-space optics... (which I don't personally recommend!)

(And if you haven't IP how are you talking to the phones between sites?)

So what's to stop you from putting a Cisco phone into auto-answer mode and 
calling it via ths Page() application?

And if a Cisco can't work in this manner, there are plenty of others that 
will.
