We have an old paging/intercom system at one of our schools that needs to be replaced. I am exploring how to use our new FreePBX VOIP system to take over that functionality and only using the phone speakers themselves is not going to do it.
Does a multi-channel (30-40 channels exist)? For example, each analog speakers should connect to a box so that I could configure an extension that would only broadcast over that particular speaker. Or am I thinking of this wrong and there is a better way of accomplishing the use of the speakers by the VOIP system while maintaining the ability to use them individually.
Thank you Jared, but I am not referring to multicast. I am referring to having multiple channels (physical connections) for multiple speakers so that I may send a page to only ONE classroom if I choose.
further , you can use your phones to page/intercom as per and use ffmpeg or similar to play scheduled bells and automatically triggered announcements bypassing the PBX , even when if it is not working.
Grandstream, Algo, Viking and a few others offer wall and ceiling mount poe IP ‘speakers’ to supplement desk phones.
