UCM6510 considers a non-ringing line with hangup activity. The default 
setting is 8000.

valid range is from -13.5 (dB) to + 12.0 (dB). The default setting is 0.

Tone Settings 
Busy Detection 
Busy Detection is used to detect far end hangup or for detecting busy 
signal. The default setting is "Yes". 
Busy Tone Count

tones to be played before hanging up. The default setting is 2. Better 
results might be achieved if 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.

default setting is "Yes". 
Congestion Count 
If "Congestion Detection" is enabled, users can specify the number of
