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 (for SBC calls) or Var.Call.Dst.UserDefined1 (for Gateway calls) 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:
1. 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 (for SBC calls) or Var.Call.Dst.UserDefined1 (for Gateway calls)
● 'Action Type': Modify
● ' Action Value': Header.X-AccountNumber
2. In the SBC CDR Format table or Gateway CDR Format table, configure the following rule:
● 'Index': 0
● 'CDR Type': Syslog SBC (SBC CDR Format table) or Syslog Gateway (Gateway CDR Format table)
● 'Field Type': Var Call User Defined 1
● 'Title': Account
3. (Gateway calls only) Configure the [GWInboundManipulationSet] parameter to "5" (i.e., value of 'Manipulation Set' parameter, above).

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