Improvement: IGMP snooping support for an efficient multicast paging


LAN switches use IGMP snooping to prevent flooding of multicast traffic. This requires that devices that want to receive multicast traffic periodically send IGMP JOIN requests.
This method is the most efficient way to distribute multicast paging traffic only to the phones that require it. I recommend adding support for the IGM snooping protocol for the GXV3380 to talk to the switch and manage multicast traffic efficiently.
