Name
Description
Outpulsing delay
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 in milliseconds.
Note: This parameter is used to match the digit receiving response time of the
PSTN PBX.
CallerID detection
Before ringing;
After ringing. The After ringing mode is generally used.
Ring relay
Whether to relay the ring of inbound call to the FXS port when applying to DID.
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 applies to DID feature.
PSTN failover
Whether to route a call to the PSTN through an FXO port when the IP network
faults or no response to the call request. Default selected.
Inbound first digit
timeout
Set the timeout of calling DTMF on FXO port for inbound calls, ranging from
10-60 seconds, with default of 24 seconds.
Answer delay
Set the delay time for sending 200 OK. It rangs from 10-60 seconds, with default of
12 seconds.
This parameter is used in combination with the Connect signal delay in Trunk >
Trunk page. See Table 2-15.
Off-hook for
rejection
This parameter is used to specify how to reject an incoming call in the 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 milliseconds,
with a default of 600 milliseconds
On-hook protection
time
Protection period following hang up of FXO port. During this period, gateway
ignores any voltage variation of 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: 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.
Busy detection
Busy tone count
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).
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.
