Unless you It was probably a Department of Defense phone. These phones looked like touch-tone, made noises *similar* to touch-tone, but were on the private DOD Autovon network. They were not pulse dialers. To my uneducated ear they were DTMF, but they were definately tone dialers. They had four extra keys for setting call priority. We had a similar setup to the one described for JFK at a radar site i.e. 'normal' phones, dial at that time, and in certain command centers, commanders offices, communications centers, etc. an additional Autovon phone, as described.
