I’m replacing a Talkswitch 48 CVA with a UCM6204. The Talkswitch unit has an audio port (1/8" I think) which is connected to a Bogen amplifier which drives loudspeakers and creates an overhead paging system. Since the UCM6204 has no such port I’d like to be able to communicate with the amplifier via an FXS port. If I connect the FXS port directly to the amplifier I get dial tone/busy signal over the loudspeaker – not exactly what I have in mind. Has anyone done this and can therefore give me some guidance? Or, is there a gateway/ATA device that will accomplish what I’m trying to do?
