I am installing a CCME 3.2 system. I have a overhead speaker paging system that is connected via an ATA-186. I can call the associated extension and get connected to the overhead speakers, but if I put that ephone (and all of the other ephones) in a paging-dn and try to dial the pagin-dn extension, I can hear myself on all of the systems phones but not the overhead speakers. Is this a limitation of the ATA device in CCME? Can an ephone on an ATA device have a pagin-dn defined.
