    With a cloud hosted server it is currently not possible to use multicast paging groups. It would be helpful if this could be setup through the SBC.

    We setup multicast paging in a template change on the yealink config. it works pretty well, and the 3CX server is hosted out in the cloud.

    DocTechAZ is correct, setting up multicast through phone template is the way to go, as an alternative use a multicast paging server like the CyberData Paging Server or ALGO 8301 may work for your needs.

    If 3CX could simply provision the listening address and allow button configuration for multicast, that is all you need. Quite simply, there is no reason why the server needs to be involved in a multicast page. Yealink and Grandstream just need the listening address configured, and a button programmed on the set to initiate a multicast page (which could be provisioned via BLF). As it sits, the only way around this is custom template, which then pulls the sets from being supported by 3CX.

    As soon as you select the option to use a SBC the multicast provision option is removed from the page.

    I'm currently working on moving an on-prem server to a datacenter for redundancy and scale out and getting multicast paging to work is our current issue.

    Well you can wait an eternity for 3CX to implement this feature, do a custom template, or get a paging adapter. You could also setup multicast forwarding over a s2s tunnel if you have that in place already for the phones.

    I've been Googling this for an hour and you nailed my issue on the head. I couldn't figure out why everyone behind the SBC had no multicast listener address. Considering the SBC allows all the phones to act like they are on a LAN, this is a rather large oversight.

    +1 Yes, lets vote this idea up. SBC is meant for bigger installs, the kind of installs where they would need MP.

    SBC works like they are on the LAN, but Multicast usually can not traverse Firewalls... it wouldn't know where to go. So the SBC almost would need to act like a repeater... to listen for a 224 on the remote network, then replay it on the local network.

    The easier way would be to just send the audio to the SBC using RTP, and have the SBC multicast it out just like the 3CX server does, rather than try to repeat it. Doing so would not be difficult at all from a programming prospective. Then the phones would only need the same multicast ports as a local phone.

    Is that even possible since it’s not on the same subnet as the server?
    If 3CX would allow a multicast BLF in the template then that would help.

    I have no expectation of the SBC to relay multicasting.

    There's some assumptions going on here. 3CX allows MC if the phones are local to the server, and doesn't if there's an SBC in play. You could very easily have problems with MC with local phones and then have the reverse where a client's network is setup perfectly and can relay MC remotely. 3CX just cannot know.

    I think the MC option should be available for LAN and SBC and safely assumed to be broken with remote phones, and a disclaimer shown that your results may vary. You could very easily have a local 3CX server and local phones and zero working multicasting.

    As to the multicasting BLF, just create a custom speed dial with the extension of the Paging Multicast ring group.
