2.6.3.1 Start
This block begins the call handling. If the Call Routing Manager calls this rule or action, then it will automatically begin with this block. Therefore, the input of this block cannot be connected. Under "Properties", all three tabs "General", "Parameters" and "Connections" tabs are available for this block.
This is how you define the parameters for "Start rule"
In this window, you can define those functions that you would like to use in the script. These functions are added in the form of a Visual Basic Script. See also 2.7 The Use of a Visual Basic Script.

The "Start rule" block only has one output with the fixed name "Start script". The block is always exited via this output.
