Yep.... ! I agree.

Will let ya know how it works out. More than likely I'll be posting with questions on how to hook the little bugger up.

Thanks!

PS:

Looked at the install guide, perhaps a bit of good news:

"After Rotatone is installed, neither the microphone nor the receiver requires shunting during dialling. In fact, a shunt would be undesirable because Rotatone reproduces a faint clicking during dialling that mimics the sound a conventional loop disconnect phone makes during dialling."
