<Unset>

The <Unset> verb allows the developer to delete a variable.

<Unset> Attributes

<Unset> supports the following attributes that change its behavior:

Attribute	Allowed Values	Default Value
history	disable, compact, full	disable
output	string (maximum 50 characters)	none

history

The history attribute determines if the <Unset> verb should be logged in the history array of the CDR. The default is to not log.

For <Unset>, both compact and full have the same effect of logging the following payload to the history array.

{
  "payload": {
    "output": "menu"
  }
}

output

The output attribute represents the variable's name.
