Customer can't connect to the Conference, while joining they get a error "Could not connect to the server". We tried "Oracle Beehive Conferencing" with at least 12 Customers only 2 were able to connect. All 10 Customer reported the same issue.
Ports 80/443 are open by default on all systems, 5224 is required by the Beehive Desktop conference client. If customer is trying to connect using Desktop client then they need to check if 5224 port is closed by any firewall running on the system.
Following document got the compatible OS list and few screen shots
