Does anybody know if I will need MCDN keycode to network a MICS using E&M DTI back to an Opt. 11. My understanding is that the PBX just needs to be setup as TIE w/ signaling as E&M and the IFC to SL1.
I see that you need MCDN for centralized vm to the Norstar but they will be using the vm on the PBX.
