Purpose

The Link item is, essentially, a grammar-activated Goto item. The Link item makes it possible to redirect the call flow based on a particular spoken word or phrase or a combination of DTMF key presses. This functionality can be helpful, for example, when you want to allow callers to go to a live operator at any point in the call flow. In this case, you might place a Link item in the AppRoot node with grammars to recognize both the word "operator" and a key press of 0. Either response by a caller would redirect the call flow to a call transfer node to dial the extension for the live attendant.

Behavior

The Link item has built-in DTMF recognition capability. This means that you do not have to use a DTMF grammar for the application to recognize a DTMF response. If you want the Link item to recognize spoken responses, you must attach an ASR Grammar item to the Link item.

You must use either one Goto item or one Throw item with the Link item. You can only use one or the other, not both.

If you use a Goto item, when the Link is activated, the application passes control to the node designated by the Goto item. See Goto.

If you use a Throw item, when the Link is activated, the application throws the event designated by the Throw item. See Throw.
