Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

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.
