1)Busy Detection
· Busy Detection
Busy Detection is used to detect far end hang-up or for detecting a busy signal.
Select “Yes” to turn this feature on.
· Busy Count
If Busy Detection is enabled, it is also possible to specify how many busy tones
to wait for before disconnecting the call. 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 will be required to release a channel. A higher setting lowers the
probability that you will encounter random hang-ups.
· Busy Interval
The busy detection interval
· 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, MyPBX will accept any regular sound-silence pattern that
repeats <Busy Count> times as a busy signal. If you specify Busy Pattern, then
MyPBX 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 (Enable detecting the busy signal frequency or
not).
· Busy Frequency
If the Frequency Detection is enabled, you must specify the local frequency.
· Polarity Detection
Configure if the call needs to be hung up when a polarity signal arrived
