SECTION 6
CONTROL TOUCHTONE
SENSITIVITY	When the voice mail system is playing and recording messages and
	prompts, it must recognize real touchtones dialed by the caller while
	screening out the false touchtones that may occur in human speech.

Because of no audible difference between the sound of dialed touchtones and spoken ones, the system can only distinguish between them by length. Dialed touchtones are usually longer than spoken ones, so the voice mail system ignores tones less than a certain length.

The voice mail system has the following minimum lengths for touchtones:

Prompt

Used when the system plays a prompt and expects the caller to enter touchtones.

Msg

Used when the system plays back a message recorded over the

￿telephone and knows that the caller might enter a touchtone. Record

Used when the system records a message and does not expect the caller to enter a touchtone.
