I had a Door Phone and Door Opening Controller on a MICS. We migrated to a BCM and the BCM will not recognize the Door phone. In the BCM documentation is referes to the Door Phone as a BTS Door Phone. I was told that ALL norstar doorphones are BST Door phones but Unified Manager will not recognize the door phone. I am stumped. Does any one know if the MICS and BCM require different door phones? If so can we still use the same DOC and what are the needed dip-switch settings?
