Ace,
I don't have a Viking device yet. I was just curious what device/model it is that allows for this.
I was trying to set up an 8568 key, that when you press it, opens a port (paging) that connects to the overhead speaker, but also (simultaneously) rings-down to a CRA or recording and play it overhead. Like... "there's a fire in the building" or "shooter onsite" or whatever CANNED recording by key press.
I know this sounds far fetched, but if this Viking device that Tech stated will work, I would like to see this device before calling anyone, so I can make arrangements on using it instead.
Any work around without having to purchase more equipment would be better. I don't think that this scenario will work in the 5000.
