Normal Calls (Cisco IP Phone-to-Cisco IP Phone)
Normal calls log three records per call. They are: EndCall plus two diagnostic records, one for
each endpoint. In the EndCall record, all fields may contain valid information. The duration will
always be non-zero unless the “CdrLogCallsWithZeroDurationFlag” flag is enabled (set to true).
The “originalCalledPartyNumber” field will contain the same directory number as the
“finalCalledPartyNumber” field.
Abandoned Calls
The logging of calls with zero duration is optional. Normally these records will not be logged. If
logging calls with zero duration is enabled, the following things should be noted.
•
If the call was abandoned (such as when a phone is taken off hook, and placed back on
hook), various fields will not contain data. In this case, the “originalCalledPartyNumber,”
“finalCalledPartyNumber,” the partitions associated with them, “destIpAddr,” and the
dateTimeConnect fields will be blank. All calls that were not connected will have a
“duration” of zero seconds. When a call is abandoned, the cause code is “0”.
•
If the user dialed a directory number and then abandoned the call before it was connected,
the “First Dest” and “Final Dest” fields and their associated partitions will contain the
directory number and partition to which the call would have been extended. The “Dest
Ip” field will be blank, and the duration will be zero.
Forwarded or Redirected Calls
The call records for forwarded calls will be the same as those for normal calls except for the
“originalCalledPartyNumber” field, and the “originalCalledPartyNumberPartition” fields. These
fields will contain the directory number and partition for the destination that was originally
dialed by the originator of the call. If the call was forwarded, the “finalCalledPartyNumber” and
“finalCalledpartyNumberPartition” fields will be different, and will contain the directory number
and partition of the final destination of the call. Also, when a call is forwarded, the
“lastRedirectDn” and “lastRedirectDnPartition” fields will contain the directory number and
partition of the last phone that forwarded or redirected this call.
Calls With Busy or Bad Destinations
These calls will be logged as a normal call with all relevant fields containing data. The Called
Party Cause field will contain a cause code indicating why the call was not connected, and the
Called Party IP and Date/Time Connect fields will be blank. If the originator abandoned the call,
the cause will be “NO_ERROR” (0). The Duration will always be zero seconds. These calls will
not be logged unless “CdrLogCallsWithZeroDurationFlag” is enabled.
