My client is a school with a large old Bogen 70V zoned 2 way paging system that they want to replace. The company that originally installed it (and has the only schematics) won't touch it and only want to sell them something new. I am against it since for the most part it works pretty good. I feel a bit of maintenance would be sufficient. They are asking for 3 bids so I need to stay in the game. One of the main issues is the tone ringers that they schedule classes with. I am at a loss on what to offer them. Normally I do Valcom for paging, but have never had to integrate timed signalling for a minimum of 6 schedules they can easily select. Oh, and they want to tie it into the phone system. I am proposing a TDE200 for the telcom side.

Any clues would be appreciated.
