Listening Volume: Adjusts the earpiece or speaker volume.
Speaking Volume: Adjusts the microphone volume.
Tone Volume: Adds a new option to make tone volume adjustable. This setting will be applied to all
tones generated by the gateway including dial tone and busy tone.
Min. FXS Hook Flash Time: It is to set the minimum flash time for FXS detecting.
Flash Time: Used to adjust the detection period for flash signals from a phone set connected to an
FXS port. For example, if pressing the HOLD key sometimes disconnects a call, increasing the “Flash
Detect Time” should fix this issue.
Enable Polarity Reversal: As a remote site answers calls from this extension the FXS port will
reverse polarity.
FXS Chip Option 1: It is to avoid mis-detecting the loop state of a subscriber line or PBX user loop by
FXS interface. In some places, the voltage of off-hook makes it mis-detect the idle state and the active
state by FXS interface. Untick this variable if it mis-detects the state by FXS interface in your place.
Ring (Early Media) Time Limit[10 - 600secs]：The timeout to cancel a call when no one answers.
Enable End of Digit Tone：The gateway will play a “Beep-Beep” tone to notify that the call is in
progress.
Early Media Treatment: If this variable is disabled, the system will send RTP immediately after a
connection with a proxy is set up. The default setting is enabled. If communicating with other gateways
encounters problems, please disable this function.
Loop Current Drop Trigger Time: It is to set the trigger time for dropping loop current by FXS port. A
setting of zero is to disable this function. It is used to avoid the line engaged if FXS port is connected to
PBX.
Loop Current Drop Duration: It is to set the drop duration.
