One MCU in Changsha Railcom with a set of platform software- VBILL, RMCC, GKM, GK, local manage platform;
One MCU in Huaihua Railcom without platform software has local manage platform
MCUs in Changsha and Huaihua cascade, when there is only chairman in one conference, the main meeting place under Changsha MCU can’t watch meeting place in Huaihua freely; or Changsha MCU and Huaihua MCU both have a chairman in one conference- that is two chairmen in one conference.
Check the accessory.
The problem is related to cascade method. One is local manage platform cascade, one is RMCC cascade.
