i have paging setup but i need to setup the multicast within freepbx 16.
i have set a multicast address 234.2.1.1:2000 i just am not sure how to get it to work in the setting under page and intercom. i do have page pro.
i do have one extension and an algo to test with
For big school we had an algo paging gateway, paged just that in the pbx and it would page over multicast to all the other algo speakers.

If you have page pro, there’s a spot for multicast addresses, make sure you have that filled. The next big thing is making sure you have built a static route from the proper device in terminal, create or edit /etc/sysconfig/network-scripts/route-interface_name.
In the file make your route like this:
234.2.1.1/32 dev interface_name
That will ensure the route is persitant.
I believe OpenPage should also enable Multicast, it is documented in the wiki: Open Page Module Wiki
Whatever router you’re going through need to support multicast forwarding if the pbx is on a different subnet as well. I was assuming that the pbx was remote from the phones in my earlier post.
i have page pro , but its hosted so not onsite. i have 4 algos and about 15 phones so if its super delayed i may build an onsite server and use multicast.
i dont think i can multicast over vpn.
I have heard read online there are ways of doing multicast across VPN but it hinges on the equipment you are using(example Ubiquiti/Wireguard, supposedly possible) but that being said this is not something I have done, and I was looking at a totally different multicast use case. I believe cyberdata makes a dedicated relay server( also built into some of their SIP paging speakers) that would physically sit onsite and recieve a broadcast then retransmit via local multicast, if programmed to do so.
