cpmCallHistorySummaryTable
The call history summary table is needed to track ended active calls. This table is needed because modem calls are not in CALL-HISTORY-MIB; the CISCO-ISDN-MIB objects do not contain information about the active calls; and the DIAL-CONTROL_MIB is not yet available.
This OID is also declared by other modules:
CISCO-POP-MGMT-MIB
