Cisco Unified CallManager 4.2(3) Call Detail Record Definition

Troubleshooting
On-Net vs Off-Net
You may have difficultly determining whether a call stays completely on the IP network or at least
internal to the local system. One way you can verify this information is to check the device type of both
ends of the call. If both are phones, you can assume that the call stayed on-net. If one device is a gateway,
you must consider the following information. If the gateway is an analog access type of device with a
POTS or station port, the call may have gone to a local analog phone or to the PSTN. You must look at
the number dialed and the dial plan to determine whether the call went off-net.
Off-Net Digits Dialed
If a call is placed out of a gateway, the digits dialed to get to the gateway may not be the digits sent to
the PSTN. The gateway may modify the directory number further. The Cisco Unified CallManager does
not receive the modified number, and the CDR does not reflect the actual digits that are sent off-net.
Troubleshooting
This section covers an issue that is related to CDRs.
CDRs Fail to Insert
Symptom
A third-party CDR application is installed, and CDRs fail to insert.
Probable Cause
The third-party CDR application may cause this issue.
Corrective Action
Alter all insert triggers for the third-party application and change them to update triggers instead of
insert triggers. This will help determine whether the issue is due to the third-party application.
