I am trying to add a paging system to my Merlin Legend 3.0. I have a Valcom 2001A and a Bogen TPU-35B. Im not sure which one i want to use, but im leaning more towards the Valcom. I have speakers and everything for both systems. I connected the Valcom to 802 on the Merlin and went into WinSPM and set the Paging line to 802. Thats about as far as i can figure out. I tried assigning 802 to one of the buttons on the phones but cannot get it to work. Any ideas?
