some findings:
- the intercom runs the same multicast route (different vlan): main switch, sub switch, videophone and it will continue to work
- "IGMP snooping" and "Multicast Querier" are turned off, if they are turned on, the videophone video traffic will stop immediately and the multicast traffic to the LM will stop within 30 minutes. With the settings off it will be fine for a few weeks.
- when restarting a client LM, the problem is temporarily solved again
