Gain to IP
Set the voice volume gain towards IP side, the default is 0. Taking
decibel as the unit, setting range is -3 ~ +3 decibels. -3 means
declining of 3 decibels; +3 denotes the amplification of 3 decibels.
Gain to terminal
Set the voice volume gain towards FXS port side, the default is -3.
Taking decibel as the unit, setting range is -6 ~ +3 decibels. -3
means declining of 3 decibels; +3 denotes the amplification of 3
decibels.
Impedance
Select the parameter of FXS port line impedance and the default
value is 600 ohm. The optional values as below:

Min.hookflas h Used by gateway to detect Hook Flash event, the default is 75
milliseconds. The gateway will ignore any flash that fall short of
the shortest flash time. Generally, this value should not be less than
75 milliseconds.
Max .hookflas h Used by gateway to detect hook flash, the default is 800
milliseconds.
The gateway will regard the flash duration between
Any flash
lasting over the longest time will be considered by gateway as
hang up. Generally, this value should not be less than 800
milliseconds.
Hook debouncing
Used by gateway to avoid the glitch of the phone status, with
default of 50 milliseconds.
When the duration from hang-up to off-hook falls short of this
value, the gateway will ignore the status variation, and consider
the phone remains hang-up status. In case of vice versa, the
gateway will ignore the status variation, and consider the phone
remains off hook status. Effective range of setting is 10~1000
milliseconds.
Ring frequency Set the ringing frequency to be transmitted by gateway to the
phone, ranging from 15 to 50 Hz, with default of 20 Hz.
Caller releas e Set the delay release time of line as caller control method, with
default of 60 seconds. Effective range of setting is 15~180 seconds.
Outpulsing delay Used when gateways FXS port is connected with the trunk
interface of PBXs. For calls from gateway to PBX, gateways will
relay the extensions to PBX after the delay set here. Setting of 0
means no extension number relay. The default is 0 millisecond.
