I'm not entirely sure about the PagePac Plus, generally speaking, we typically use an ATA port connected to a Bogen TAM-B (or an Avaya UPAM). Connect one of the ports of the ATA to the Tip/Ring ports of the TAM-B, then connect the paging output of the TAM-B to the paging amp. Assign a DN to the ATA port connected to the TAM-B. When you call the DN, the TAM-B will see ring voltage and open up a talk path to the page amp.
