Issue Description
customer reported that the conference hangs suddenly and also the MCU 8650 boards are offline as there is no lights blinking on the subboards. customer was using this MCU for conference for their private network. everything was running smoothly and suddenly this happens. customer said when they restart the MCU its work fine for sometime and then again suddenly MCU goes offline.

customer have a 6 party conference of higher management so the IT team tried to test the system before the conference. when they tried to make a conference call they were unable to make. when they check the hardware all the lights of DSPs on MCU boards were off. so they tried to reboot the system after which system was working fine until after sometime system stops again and conference hangs and the MCU lights again went offline.
When this kind of issue occurs either the hardware is faulty or the software. as hardware is difficult to change first try to upgrade the firmware of the MCU to some other verison. because sometimes softwares stops working and some error can come up in the software. so if after upgrading software system still remains offline then try to change the boards.
