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 is a feature that enables multiple SIP users to listen to a page from a shared multicast IP address. In a multicast page call, one-way audio is set up from the sender to the listeners, but the listeners cannot talk to each other. This feature is ideal for quickly broadcasting important messages to many users within a local area network (LAN).
The sender and listeners must be located within the same LAN to use multicast paging. This means that devices must be connected to the same network switch or through a virtual LAN (VLAN) configuration. It's important to note that multicast paging may not be available on all SIP phones or VoIP platforms.
If you're using Grandstream phones, you can find detailed instructions for setting up multicast paging in the Grandstream GXP Devices. This guide provides step-by-step instructions for configuring the feature on Grandstream devices.
If you're using Cytracom D2 phones, you can find detailed instructions for setting up multicast paging in the Cytracom D2 Devices. This guide provides step-by-step instructions for configuring the feature on D2 devices.
In summary, multicast paging is a valuable feature for quickly broadcasting messages to many users within a LAN. To use multicast paging, ensure that all devices are connected to the same network switch or through a VLAN configuration. If you're using Grandstream phones, refer to the user guide for instructions on setting up multicast paging.
