CDR Customization using Call Variables Example

This section provides an example of customizing the CDR to include the 'Var Call User Defined <1-5>' field, whose value is obtained using call variables in Message Manipulation rules.

The example includes the following:

■

Uses the call variable Var.Call.Src.UserDefined1 in a Message Manipulation rule to store the value of the SIP header "X-AccountNumber" received in a 200 OK response.

■

Customizes the CDR format to add the CDR field "Var Call User Defined 1"', renames it "Account", and obtains its value from the call variable above.

➢

To customize CDR using call variable:

In the Message Manipulations table (see Configuring SIP Message Manipulation), configure the following rule:

●

'Index': 0

●

'Name': Store X-AccountNumber header

●

'Manipulation Set ID': 5

●

'Message Type': Invite.Response.2xx

●

'Action Subject': Var.Call.Src.UserDefined1

●

'Action Type': Modify

●

' Action Value': Header.X-AccountNumber

In the SBC CDR Format table, configure the following rule:

●

'Index': 0

●

'CDR Type': Syslog SBC

●

'Field Type': Var Call User Defined 1

●

'Title': Account

The following shows an example of a received SIP 200 OK response message with the X-InContact-BusNo header:
