Need Help interpreting the EVENT on a Call

Hello,

A call dropped in a middle of a conversation. I looked at the call events in the CDR report and I am having a hard time to interpret what really happened on the call. There are multiple HANGUP events but I couldn’t tell if it is a hangup on our end or the other end. Can someone help me interpret this?
Thanks in advance.

You would have to look at the logs around that time. CEL is not that specific
