There was 2 MCU which was not connected to each other in the former network, the customs need the 2 MCU mutual connect and control. After they had connected and appointed the master and subordinate MCU, the subordinate MCU could enter the conference, but the two MCU can’t see each other.
The MCU has entered conference, but can’t see the video may because:
1,It has not really entered conference, wrong information.
2,Tt has entered conference, but the capability miss match
Do local loopback at the two grade MCU, there was no sync problem, so the first likelihood was eliminated; then we examined the capability settings of the MCU and found there was a lot of differences between them, after correcting and restarting, we could see the image.
The two grade MCU has the different capability setting to control each other.
