i have a valcom v-9924b commom audible ringing unit hooked up to a CISC with 6.1 software. customer need's co ring over paging. i can run the paging through the unit OK, but not the ringing. I have the v/s s/v pair off the DN block and have tried all the ways to hooking it up to the valcom unit, but still not working. i have even tried an other unit, still no good. i have set the aux ring in the line program to "y". i know i'm missing one little thing but i have about 5 hr hooking and unhooking jumper's.
