I have a customer on a 500 acre church camp. The camp office needs phone service to lodges, the kitchen, the pool, the maintenance building from the office. They want the exension to have dial 9 for call restriction, but allow them to use the phone sets as internal intercom to each location. One of the lodges is located 1 mile from the office. A straight digital phone system such as Nortel CICS and MICS does not have enough power to maintain the extensions without static. It came to me the Partner is a hydrid phone system that uses analog phone sets. I thought since analog has a higher power generated it could handle the distance of the extension. I was looking a Partner II or Plus due to the church camp of course is very frugal.
