Our phone system is the same -- the flash button sends some digital code to the electronic equipment, which then flashes the CO line being used. In ours, the duration of the flash is programmable. The default is, I think, 1.5 or 2 seconds, which actually disconnects the line. However, it can be reset to very short intervals which would perform a real flash. The button serves a dual purpose, though. When making an internal (intercom) call, the flash button *always* terminates the call and provides new internal dial tone. Since we don't have any need for a hookflash on the outside lines, it seems reasonable to have the button disconnect the call in both situations. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.
