Check VLAN Settings
For multicast paging to work all the devices (Polycom phones and Algo speakers) must be on the same VLAN.
Ensure that Poly/Polycom desk phones in the paging group are on the same VLAN. You can press and hold 1-4-7 on a Poly phone to bring up its details including VLAN information.
Ensure that all Algo speakers in the paging group are on the same VLAN. You may need to make adjustments to the VLAN setting in the Algo interface. VLAN settings are located under AdvanceSettings >> Network.
Check IGMP Snooping Setting on Switches
If the devices in your paging group are on different switches in your network, you may need to look at IGMP snooping setting.
