Is this even possible to do? I asked in a previous post how to extension dial only for a phone in the drivers lounge. This part is working great. They are asking if someone can call or page this extension so the intercom of the phone comes on and they can talk without anyone having to pick it up. If you can picture drivers in a lounge area, another extension (shipping office) can just speak through the drivers lounge phone as an intercomm or paging device without having the phone ring and someone pick it up. This way they can address everyone in the room. Have in IP 500 using IP Office.
