Hi Jon,

how is the existing intercom implemented? Is it on the phones or 
separate speakers?

If it is a paging system wired into the Nortel, you may be able to reuse 
it via an ATA,

If it's done through the phones, try 
http://www.voip-info.org/wiki/index.php?page=Asterisk+Paging+and+Intercom 
for ideas

That is, once you've bridged the ethernet across the 3-400 yards. You 
can use fibre, wireless or Thicknet. Fibre is the most robust, wireless 
is the cheapest and Thicknet, well, good luck getting the parts! :-)

regards,

Drew
