With D2's using WiFi as the primary connection it is recommended that the network containing these devices has a well established mesh network or access point system to accommodate the increased congestion created by a multicast page. Otherwise it is recommended to disable multicast traffic for WiFi endpoints via the router or access point. Therefore inhibiting any D2's, using WiFi as the primary connection, from receiving these pages.

Multicast paging allows different SIP users to listen to a page from a common multicast IP address. In a multicast page call, one way audio will setup from sender to listeners, but the listeners cannot talk to each other. The sender and listeners must be located within the same LAN.
