Bell_USA, DTMF).
Polarity: Start when a polarity reversal is started (Caller ID
Signaling: V23_UK, V23_JP,DTMF).
Before Ring: Start before a ring is received (Caller ID
Signaling: DTMF).
This option defines the type of Caller ID signaling to use. It
can be set to one of the following:
 Bell_USA: bell202 as used in the United States
 v23_UK: suitable in the UK
 v23_Japan: suitable in Japan
 v23-Japan pure: suitable in Japan
 DTMF: suitable in Denmark, Sweden, and Holland
Busy Detection is used to detect far end hang-up or for
detecting a busy signal. Select "Yes" to turn this feature
on.
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.
The busy detection interval
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. If a Busy Pattern is not
specified,The system will accept any regular sound-silence
pattern that repeats <Busy Count> times as a busy signal.
If you specify Busy Pattern, then the system will further
check the length of the tone and silence, which will further
reduce the chance of a false positive disconnection.
Used for Frequency Detection (Enable detecting the busy
signal frequency or not).
If the Frequency Detection is enabled, you must specify
the local frequency.
The call will be considered as "hang up" on a polarity
reversal.
