Think for a second... how would that even work?? Mutlicast paging works because it's a one-way audio stream. Phone A begins transmitting it's audio to the entire Multicast group, and anyone is free to listen to it simply by playing back the packets received on that port/address. To add Intercom you would make it expontentially more difficult as each responding person would have to have their own multicast port/address to reply on, and then the phones would have to all be aware of those, and then they would have to locally bridge/merge all of the audio together.

I don't see how even if Yealink decided to somehow do all of that it would be any faster/more efficient than using the intercom through Asterisk (which is literally just a SIP call between two phones that gets auto answered). How long of a delay are you experiencing when doing an intercom through the PBX? It should be no slower than making a phone call... if it is, then you need to look at your configuration and find out what you're doing wrong.
