Cisco 7940/7960 Multicast Paging

[tech23]

Does anyone know if the Cisco 7940 & 7960 support multicast paging when converted to SIP and used with 3CX? If so, do they support multiple paging groups?

I know the cisco handsets support multicast. When used with cisco callmanager you can setup third party paging solutions that use multicast. My experiance was with SCCP though, not sip. I would imagine even with sip the phones support multicast but I have never used a 79xx with 3cx
