We are trying to connect a Cisco Switch port, controlled by Cisco Call manager, to a Bogen ZPM3 overhead paging module. We have tried connecting FXS ports programmed as Loop Start, POTS, and Ground Start configurations. When the Directory Number is dialed, the port sends ring voltage. We have tried to find out how to make the port simply act as an off-hook line. When a craft-test-set is connected to the ZPM3, overhead paging works. We know that we could use FXO ports to connect the switch to the ZPM3. We have two other VoIP sites that connect to overhead paging. Checking the programming shows that FXS ports programmed as POTS lines are successfully used at those sites.
If you have experience connecting a Bogen ZPM3 to a Cisco Switch, Using Call Manager, please advise.
