“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 disconnection.
·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.
·Hangup Polarity Reversal Detection
The call will be considered as “hang up” on a polarity reversal.
2) Answer Detection
·Answer Detection
Answer Detection settings are configured for accurate billing. If the PSTN trunk sends
polarity after answering the call, users can choose "Polarity Detection"; or else choose
"Ring Detection", and configure the detailed settings according to the PSTN line ring tone.
3) Caller ID setting
·Caller ID Start
This option allows you to define the start of a Caller ID signal:
Ring: Start when a ring is received (Caller ID Signaling: 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).
·Caller ID Signaling
This option defines the type of Caller ID signaling to use. It can be set to one of the
following:
