Description: The list of disconnect cause codes that the H.323 subsystem has received. A disconnect can originate either from the far-end gateway or from the opposite call leg on the local gateway. Whenever a disconnect occurs the entry in the table will be updated by the agent. The cause for disconnect is mapped to one of cause codes and if an entry for the cause code exists in the table, number of disconnects is incremented for that entry, otherwise a new entry is made with cause code as index.
