That is the tricky part of what you're trying to do. You basically want paging to override everything, but of course if you say that, how does the calling phone know that you are using it to page, and not just on a call to somebody else that should be over-ridden.

When you do the multicast from the phone itself the phone can tell, because you have triggered the multicast from it. When you just dial an extension on FreePBX though the phone has no way to know that it is triggering the multi-cast...

What is the actual reason for having FreePBX do the multicast instead of the phone directly? Without some special feature or support from Yealink (which seems unlikely since they would just say use the multicast on the phone itself) I don't see how you are going to make this work the way you are describing....
