We are running UCM 6.1.2 and using our legacy speakers for paging. The speakers are hooked up to a Bogen TAM B which runs back to an FXS port on our voice gateway. This solution works fine most of the time. However there are instances where when someone dials the paging DN, there is a loud beep before their voice is heard. Also we have an issue sometimes where when someone dials the paging DN we get a busy tone over the speaker system. I've checked the TAM B and the preannounce is set to off. Anyone have any ideas on these two issues?
