I have a Nortel T7316E phone at work. When I am on speakerphone, the volume is too loud even when I lower it to the minimum level on the adjustment bar. How can adjust the min volume to a lower level?

Well ~ eagleeigh731 has it mostly correct, do what he said to do and get into the programming --> find SYSTEM PRGRAMMING --> hit next until you find CHANGE DNs--> OLD DNs (this is the old extn#) 222 then type in NEW DN 431--> then hit the end or release button.
Voila your new extension is now there... to check dial FEATURE 0 then press the intercom button, the new extension should be there.
