Ringer of the Call Director : tested directly on the phone line but nothing works, maybe it's too old. Sometimes I have a single movement of the ringer but it stays blocked and not really rings... But I'm not sure about the exact wires to use (4 existing, red+black+2 grey), please confirm color by color. Ringing voltage is up to 90V AC ? So I could test with any power transformer directly because I have burned DSL adapter when testing...

Call Director with 4A : I have a 223 connecting box, wires details are also needed.

To Ed : anything new about your 82 connecting block for my 2565hkms, I'm still interested and only need the shipping costs.
