Example of Call Variables for CDR Customization

This section provides an example of using a call variable to customize the Syslog SBC (signaling) CDR. 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 SBC CDR format to add a CDR field titled "Account" whose value is obtained from the call variable, Var.Call.Src.UserDefined1 used in the Message Manipulation rule.

➢

To customize CDR using a 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': 0

●

'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:
