I was asked the question below and a suggestion of overhead paging system or broadcast voice message was not accepted. The system is Call Manager Business Edition. Thought I will ask before I shut it down as not possible.
"We would like to be able to page in the front offices, for Lockdown, Evacuation, and First Aid situations. Ideally the page would be broadcast over the phones' speakers without having to lift the handset. Can such a capability be incorporated into our phones and phone system?
Maybe record an audio file of each emergency announcement and broadcast to all, or a selected group of, phones as a ring tone?
For example, I need to initiate a lockdown.... I dial a special extension and every phone in the front office would ring with the prerecorded message "lockdown, lockdown, lockdown..." And perhaps if someone were on the phone, the message could interrupt their conversation. "
