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

Known Issues

Cisco CallManager Release 3.0(1) has several known issues with the CDR data. A few of these are listed here.

IP to Device Name Translation

The CDR table lists IP addresses for the endpoints of a call. These IP addresses are not easily converted to device names so that the type of device can be determined.

OnNet vs. OffNet

It is difficult to know if the call stayed completely on the IP network, or at least internal to the local system. One clue is to check the device type of both ends of the call. If both are phones, then one can assume that it stayed OnNet. If one is a gateway, then more assumptions must be made. If the gateway is an Analog Access type of device with a POTS or station port, then the call might have just gone to a local analog phone, or might have gone out to the PSTN. Look at the number dialed and correlate this to the known dial plan to estimate if the call went OffNet. Otherwise, the call probably went OffNet.

OffNet Digits Dialed

If a call is placed out a gateway, the digits dialed to get to the gateway may not be the digits sent to the PSTN. The gateway may be intelligent and modify the directory number further. If this is the case, Cisco CallManager does not know, and the CDR will not reflect the actual digits sent OffNet.

Fields in a Call Detail Record

This section defines all fields in the current records. The field types are those used by

Cisco CallManager, and not necessarily those defined in the CDR record in the database. The database field definitions are adequate to store the data, but the interpretation of the data should take into account the field types defined here.

All unsigned integers are 32bit unsigned integers.

Field Data Conversions

There are some fields that require conversion from decimal format to another format for displays. This appendix defines their values, and how to convert them or where to get information on how to convert them.

Time Values

All time values are represented as unsigned 32 bit integers. This unsigned integer value is displayed from the database as a signed integer.

This field is a time_t value that is obtained from the Windows NT (2000) system routines. The value is a coordinated universal time (UTC) value, and represents the number of seconds since Midnight (00:00:00) Jan. 1, 1970.
