SYMPTOMS
Clients attempting to join an H.323 fallback-enabled conference that is hosted on another conferencing server that is installed into a separate Microsoft Windows 2000 site, cannot see or hear other conference participants.
CAUSE
The connection between the client, the client's local Multipoint Control Unit (MCU)/bridge, and the hosting server does not have multicast connectivity capabilities. This is because the infrastructure does not pass multicast traffic between subnets.
RESOLUTION
Enable multicast capabilities between the two conferencing sites.
