Hello everyone. I am working on installing a Mitel SX-200 at our Battleship Memorial and I'd like to connect it to an extension on our Elite 192. I got some used equipment on E-bay that included an SLT module but I can't find anything in the documentation manuals on how to hook it up. The single line side has two terminals, tip and ring, yes? The ESI plug has 4, for what? Thanks for your time. Terry
PS I did read somewhere that I will need to program the extension as an SLT, is it that easy?
