Within the last year we installed a Cisco phone system (CUCM 7.X, Unified Messaging) and we have an old paging system (amplifier and speakers) that we want to connect up to the Cisco phone system. Our vendor configured a port on our VGA224 to do the paging. When we connect the paging unit up to this port, you can hear a dial tone over the buildings speakers. Is it possible to have this extension sit quiet until someone calls it? Does this extension need to be assigned to a phone? We are looking into 3rd party solutions but that will be down the road a ways. Any guidance would be appreciated. Thanks.
