SUMMARY

Instructions on how to accept "help" utterances, and provide contextual help to the caller.

SYMPTOMS

An application needs to accept the "help" utterance at any prompt and play contextual help audio.

RESOLUTION

The preferred way to accomplish this is to use a built-in element that inherently supports the "help" utterance (e.g. a Form element, etc.) in all cases where the "help" utterance needs to be supported.

While not recommended, global help functionality could also be implemented using a Hotlink element that is configured to respond to the "help" utterance.  This Hotlink should then exit to an Audio element with a dynamic configuration.  The dynamic configuration should examine the call flow history, and set the appropriate help audio to be played, based on the current position in the call flow.  Once the Audio element is done, it should exit to a standard Decision element that should branch to the previous location in the call flow (also by looking at the call flow history).  Note that this method is not preferred because it becomes unwieldy in large callflows, due to excessive branching.
