The Cisco IP Phone 8861 and 8865 utilize active mode primarily, but if there is an associated client that is in power save mode,
then all multicast packets will be queued until the DTIM period.
With multicast, there is no guarantee that the packet will be received the by the client.
The multicast traffic will be sent at the highest mandatory / basic data rate enabled on the access point, so will want to ensure
that only the lowest enabled rate is configured as the only mandatory / basic rate.
The client will send the IGMP join request to receive that multicast stream. The client will send the IGMP leave when the
session is to be ended.
The Cisco IP Phone 8861 and 8865 support the IGMP query feature, which can be used to reduce the amount of multicast traffic
on the wireless LAN when not necessary.
Ensure that IGMP snooping is also enabled on all switches.
Note: If using Coexistence where 802.11b/g/n and Bluetooth are being used simultaneously, then multicast voice is not
supported.
