Cisco Unified CallManager 4.2(3) Call Detail Record Definition

OL-10659-01

Cisco Unified CallManager Configuration

Call Clearing Causes

The CDR record includes two clearing causes: OrigCause and DestCause. When the originating party

clears the call, the OrigCause gets populated. When the terminating party clears the call, or the call is

rejected, the DestCause gets populated. When unpopulated, the cause value shows zero.

The “Cause Codes” section lists the calls clearing cause values per ITU specification Q.850. For on-net

call legs, the Cisco Unified CallManager determines the cause value. For off-net call legs, the far-end

switch determines the cause value.

IP Addresses

The system stores IP addresses as unsigned integers. The database displays them as signed integers. To

convert the signed decimal value to an IP address, first convert the value to a hex number, taking into

consideration that it is really an unsigned number. The 32-bit hex value represents four bytes in reverse

order (Intel standard). To determine the IP address, reverse the order of the bytes and convert each byte

to a decimal number. The resulting four bytes represent the four-byte fields of the IP address in dotted

notation.

Note The database displays a negative number when the low byte of the IP address has the most

significant bit set.

For example, the IP address 192.168.18.188 displays as -1139627840. To convert this IP address,

perform the following procedure:

Procedure

Step 1 Convert the database display (-1139627840) to a hex value.

The hex value equals 0xBC12A8C0.

Step 2 Reverse the hex bytes, as shown below:

CO A8 12 BC

Step 3 Convert the bytes from hex to decimal, as shown below:

192 168 18 188

Step 4 The IP address displays in the following format:

192.168.18.188

dateTimeConnect UTC This field designates the time that the devices

connect and speech begins. This field shows a

zero if the call never connects.

dateTimeDisconnect UTC This field designates the time that the call

disconnects. This field shows a zero if the call

never connects.
