end hangup or busy signal.
Busy Count
If Busy Detection is enabled, it is also possible to specify
how many busy tones to wait for before hanging up. The
default is 4, but better results can be achieved if this setting
is set as 6 or 8. Higher value requires more time for
detection, but lower the probability that a false detection may
occur.
Busy Interval Set the busy detection interval.
Busy Pattern
If Busy Detection is enabled, you need to specify the
cadence of the busy signal. If a busy pattern is not specified,
the system will accept any repeating sound-silence pattern
as a busy signal. If a busy pattern is specified, then the
system will check the length of the sound and the silence
patterns, which will further reduce the chance of a false
positive.
Frequency
Detection
Enable or disable Frequency Detection, it is used for
frequency detection.
Busy Frequency
If Frequency Detection is enabled, you must specify the local
frequency.
Hangup Polarity
Detection
Enable or disable Polarity Detection. The call will be

Answer Detection Type
Answer Detection
Type
Answer Detection settings are configured for accurate billing.
Select which type to detect the call as answered.
1) Default.XT-800FXO Gateway will start to charge once
you grab the PSTN trunk to call out, whether the call is
answered or not.
2) Polarity Detection: If the PSTN line supports polarity, you
can choose "Polarity detection". When the callee answers
the call, the provider will send a polarity signal, and then XT-
800FXO Gateway starts to bill.
3) Ring back Tone: If you choose this option, XT-800FXO
Gateway will charge the call according to PSTN ring back
tone detection. When the "ring duration" or the "ring interval
duration" detected on XT-800FXO Gateway is larger than
the standard or custom parameters, the call is detected as
ANSWERED.
*Standard parameters: when you configure the "Tone Zone
Settings" you get the country's standard tone parameters.
Custom Ring Tone
Enable or disable Custom Ring Tone. If the custom ring tone
is enabled, you need to configure the following settings
according to the ring back signal.
Max Ring
Duration
Max duration of the ring tone.
