One of them is the "Hangup cause":

Hangup causes

NORMAL_UNSPECIFIED - This cause is used to report a normal call event and the call is getting hung up after conversation. It indicates there is no error on the telecom side.

UNALLOCATED_NUMBER - This cause indicates that the person called could not be reached because, either the number is not in a valid format, or the number is not currently allocated/assigned to anyone.

NO_USER_RESPONSE - This is when the called person didn't respond to the call with in certain time limit (decided by the telecom operator, we don't have much control on it)

NO_ANSWER - It's similar to no user response, but In NO_USER_RESPONSE, the telecom operator doesn't even get an acknowledgement if the called person was alerted of an incoming call. But in case of NO_ANSWER, the telecom operator knows the called person is alerted of the call but no one picks up.

USER_BUSY - This cause is used to indicate that the called party is unable to accept another call because they are busy in another call.

NORMAL_CLEARING - This cause indicates that the call is being cleared because the call is over for right reasons like conversation is complete.

NORMAL_TEMPORARY_FAILURE - This cause indicates that the network is temporarily not functioning correctly for this VoIP call to establish correctly.

CALL_REJECTED - This cause indicates the call is rejected by the person who was called.

ORIGINATOR_CANCEL - This happens when the call is canceled by the person who made the call.

INVALID_NUMBER_FORMAT - This cause indicates the number for the dialed call is not in a valid format.

RECOVERY_ON_TIMER_EXPIRE - This cause is often associated with NAT problems and indicates the error handling procedure for the call has been initiated.

INTERWORKING - This cause indicates that an interworking call (usually a call to SW56 service) has ended.
