Intercom paging group problem

[Alexandre Peloquin]

We have an intercom paging group with 13 members. When we do an intercom not all phone ear the paging.

The problem is intermittent and it's not always the same phones.

The 3CX is hosted at Google Cloud and the client at a 3CX SBC locally. The router is a Fortinet 50E and they have a 100/100 fiber internet connection. The 3CX system is the latest version.

We configured Traffic Shapping in the router.

I would like to know if anyone has ever experienced the problem and how if you have solved it.

What phones and are the on the stock firmware/templates? Traffic shaping is irrelevant, but if it passes the firewall checker would be good to know.

It is Yealink T46S phone with stock firmware. Do you if we can send multicast paging over SBC 3CX?

I found a post, they have did it.

I will try this

You are best to configure through a custom template because the 3CX template will override the settings. So if you configure them through the web interface of the phone they will be lost in 24 hours unless you disable provisioning of the phone.

The settings are on the yealink phone under "directory" "Multicast IP". For the template edit this line:

"multicast.paging_address.1.ip_address =" and put the values you want to use for the multicast IP such as "224.0.0.1:5001"

Then pick a DSS key to put the "Page" key and set the type to "paging" and the value to the same Multicast ip/port "224.0.0.1:5001" with "Page" as the label. Through the template locate the DSS/BLF key you want to configure it as and set as follows (replacing X for the BLF key to use):

linekey.X.type = 24
linekey.X.value = 224.0.0.1:5001
linekey.X.label = Page

Not required but I suggest the following additional settings for the Multicast Listener. This will set the phone so that if people are talking it will not interrupt an active phone call.

multicast.receive_priority.priority = 0
multicast.receive_priority.enable = 0
