We have a new install of v15.5 with Yealink T46S handsets. I've created a multicast paging group just like we have on our other 3CX installs, and verified the T46S phones are configured to listen for multicast on the correct IP address. However, when we try to page via the multicast group the call fails with a "Busy Here" message on the Yealink. I've checked all of settings in the Page group and Yealink phones with other installs that are working, but don't see any differences. I'm just wondering if anyone else has seen this or has any ideas?

Thanks!

Perhaps the network doesn't allow multicast traffic?

As a test - setup a Yealink button one one device for Multicast Paging using the Yealink functionality instead of the PBX. If this works, you can rule out the network.

How many phones do you have? You can setup a standard paging group without multicast sub 64 end points.
Not a fan of this... too much variation in the pickups of the handsets causing bad echo at times.
 
I've personally never experienced any issues with the standard paging group with 3CX and I've done a few.

I know However that you may get these sorts of issues if:

* Phones are in different network segments/locations.

* Firmware versions varies per handset.
 
before you spend alot of time on this, let it rest, lets say until next Wednesday... hint hint...
