Ring relay
Select whether to relay the ring of inbound call to the FXS port when the
Inbound handle
mode for the FXO port is selected as
Direct
. The default is
Phone ring independently
.
Busy line handle
Either a voice prompt or hanging up can be applied to FXO port when an incoming call goes
to the FXS port which is in busy. This only applicable when the
Inbound handle
mode for
the FXO port is selected as
Direct
.
PSTN failover
Select to route a call to the PSTN through an FXO port when the IP network fails or if there
is no response to the call request. Default selected.
Inbound first digit
timeout

seconds, with default of 24 seconds.
Answer delay

seconds.
This parameter is used in combination with the

Trunk
page. See Table 2-17.
Off-hook for rejection
This parameter is used to specify how to reject an incoming call in the
Direct
mode
(see Table 2-17) for the FXO port.
For inbound calls to an FXO port, if the associated FXS port is busy, the gateway will hang
up after off hook according to the time set by the parameter, so as to refuse the upcoming
call. The duration of the off hook is 500~5000 milliseconds, with a default of 600
milliseconds
On-hook protection
time
Protection period following hang up of FXO port. During this period, the gateway ignores
any voltage variation of the line. Value range is 100~5000 milliseconds, the default is 400 in
milliseconds.
Polarity detection.
Choose whether to activate the detection of reverse polarity signal of FXO port. Note the
detection will work only when the trunk supports polarity reversal.
Caller number sending
mode
DISPLAY
: include the incoming call number detected at the FXO port in the Display
field and send it to the peer end. The From field carries the phone number associated with
the FXO port.
FROM
: include the incoming call number detected by FXO in the From field and send it
to the peer end. No Display information is carried.
Busy detection
Busy tone count
Set the number of consecutive times the gateway detects busy tone signals.
Gateways will regard the busy tone signal with the repeat times specified here as a hang-up
signal. Default is 2, effective range is 2 ~ 5(cycle).
Tone-on duration
Set duration of busy tone signal, the default is 350 in milliseconds.
Tone-off duration
Set the interval time of busy tone, the default is 350 in milliseconds.
Detect dual-frequency
busy tones
To detect dual-frequency busy tones.
Busy tone frequency
If
Detect dual-frequency busy tones
is enabled, you need to specify the frequency to be
detected.
Unit: Hz.
