·Busy Count
If Busy Detection is enabled, it is also possible to specify how many busy tones
to wait for before disconnecting. The default is 4, but better results can be
achieved if set to 6 or even 8. Remember, the higher the number, the more time
required to release a channel. A higher setting lowers the probability that you
will encounter random hang-ups
·Busy Pattern
If Busy Detection is enabled, it is also possible to specify the cadence of your
busy signal. In many countries, it is 500msec on, 500msec off. Without Busy
Pattern specified, MPBX will accept any regular sound-silence pattern that
repeats <Busy Count> times as a busy signal. If you specify Busy Pattern, then
MPBX will further check the length of the tone and silence, which will further
reduce the chance of a false positive disconnect.
·Frequency Detection
Used for Frequency Detection (the caller id signal).
·Busy Frequency
If the Frequency Detection is enabled, you must specify the local frequency.
