This table provides the H.324 extension to the call
history table of IETF Dial Control MIB. It contains H.324
call leg information about specific voice encapsulation

An entry is added to the table when its associated call
history entry in the IETF Dial Control MIB is created and
the call history entry contains information for the call
establishment to a voice encapsulation peer with video
call information type.
The entry is deleted when its associated call history
entry in the IETF Dial Control MIB is deleted.
