Ok, I am glad someone said "Rube Goldberg" before me! Thats just the way it is with phone systems sometimes. But I'm confused about this cutting of the wire. Right now, withOUT the BHEU installed, I can answer call by picking up the handset or by hitting the speaker button. What I'd like is to be able to add a third option, to pick up via the headset, but in doing so I don't want to disable the possibility that an hour from now I'm going to want to use the handset. It sounds like you're saying that once you cut that wire, you can't use the handset? Or no? Please let me know before I do something regrettable! Thanks.
