My scenario is an IP Office 500 v2 with 9.1 firmware. The system is setup as VoIP, and only used as an intercom system. I am trying to page to overhead speakers and phones at the same time. I am using a Bogen DFT feedback eliminator since some phones are close to speakers, and interfaced with a TAMB powered by a 250-watt amplifier. I have created an analog station port using IVR and created a short code that pages to an extension (*80 dial extension 400). I then created a paging group for the phones (*81 group 500). I can page to the phones, and to the overhead separately. But can’t seem to get the paging to work together. Any help is appreciated. Thanks.

The way you've set up the Analogue Extension - IVR.....
This is a regular RINGING single line telephone extension (IVR gives it a reliable disconnect when you're finished paging)
So when you dial the shortcode *80, OR dial the extension 400, the single line station RINGS. The TAM-B ANSWERS. Then it couples the audio on the line into the input of the Digital Feedback Eliminator, which feeds into the input of the amplifier.
As long as the Analogue Extension is set up and needing to ring and be answered, it won't function as part of a hunt group that pages multiple multiline telephones as well.
Change the Analogue Extension to Paging Port, and you will have an audio output to feed into the input of the Digital Feedback Eliminator. However, you may also need to add a 600-ohm matching transformer between them, or a 680-ohm resistor across Tip and Ring.
The next thing to think about..... Is simultaneous paging really going to work with a Digital Feedback Eliminator connected to the Loudspeaker portion? The phones are going to get the page in real time, the loudspeakers are going to get it after the time delay
