I have nortel t7316's and we purchased a plantronics cs50 with lifter. Installed it as plantronics directed. It works great except for incoming calls, we have to hit the button on the earpeice as well as the headset button on the phone.This is a carlot where salesman are all over the building. I like the wireless but it defeats the purpose of wireless if i have to be by the phone. What i want to happen is when a call comes in the salesperson just hits the button on the earpeice to answer the call. Is this the wrong model of headset for my nortel phones? If so can anyone recommend the right one that will do what i want? Or is it a phone promming change that needs to be done?
