Function:

If there is a busy tone on the line after dialing, this event is raised.

Parameters:

LineIndex: The line on which the event occurs.

Description:

VoiceAngel "listens" to the line to assess what is happening. A number of factors can affect how it interprets what it "hears".

Typically, line quality, exchange technology, and modem type, are factors that software cannot do much about. But there are factors that CAN be adjusted.

If you find that your VoiceAngel application fails to recognise a Busy signal and raise this event on it, you should consider adjusting the values for UpFrequency, DownFrequency, SilenceSwing and Awake.
