Description
Set the parameter of FXO impedance. The default is 600
settings are:
Complex (default value)

 (Ohm)
600

 (Ohm)
900

Set the time interval between the FXO going off-hook and start for outpulsing of
the first digit to the PSTN. The default is 600 ms.
Note: This parameter is used to match the digit receiving response time of the
PSTN PBX.
Before ringing;
After ringing. The After ringing mode is generally used.
Whether to relay the ring of inbound call to the FXS port when applying to DID.
The default is Phone ring independently.
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 applies to the DID feature.
Whether to route a call to the PSTN through an FXO port when the IP network
faults or there is no response to the call request. Default is selected.
Set the timeout of calling DTMF on FXO port for inbound calls.
The range is 10-60 sec. The default is 24 sec.
Set the delay time for sending 200 OK.
The range is 10-60 sec. The default is 12 sec.
This parameter is used in combination with the Connect signal delay in
Trunk > Trunk page. See Table 2-15.
This parameter is used to specify how to reject an incoming call in Direct mode
(see Table 2-15) 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 ms, with a
default of 600 ms.
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 ms. The default is 400 ms.
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.
DISPLAY: includes the incoming call number detected at the FXO port in the

Display field and sends it to the peer end. The From field carries the phone
number associated with the FXO port.
FROM: includes the incoming call number detected by FXO in the From field

and sends it to the peer end. No Display information is carried.
Set the number of consecutive repeat 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).
Set duration of busy tone signal, the default is 350 ms.
Set the interval time of busy tone, the default is 350 ms.
To detect dual-frequency busy tones.
