Tone Settings
Busy Detection is used to detect far end hangup or for detecting busy signal. The
Busy Detection
default setting is "Yes".
If "Busy Detection" is enabled, users can specify the number of busy tones to be
played before hanging up. The default setting is 2. Better results might be achieved if
Busy Tone Count set to 4, 6 or even 8. Please note that the higher the number is, the more time is
needed to hangup the channel. However, this might lower the probability to get
random hangup.
Congestion Congestion detection is used to detect far end congestion signal. The default setting
Detection is "Yes".
If "Congestion Detection" is enabled, users can specify the number of congestion
Congestion Count
tones to wait for. The default setting is 2.
Select the country for tone settings. If "Custom" is selected, users could manually
Tone Country configure the values for Busy Tone and Congestion Tone. The default setting is
"United States of America (USA)".
